00:00		masak	blr, wobbly neighbournet...
00:01		lue	blr?
00:01		masak	as in, 'yuck'. :)
00:02		lue	does the tester have a built in ETOOLONG type situation?
00:02		masak	no.
00:02		masak	you'll have to ^C
00:03		* lue	will now hunt w/ masak for bug
00:03		* masak	might have just found it :/
00:03		masak	yup.
00:04		masak	it was yet another instance of RT #73034.
00:04		masak	should have seen that one coming...
00:06		masak	pushed. try pulling, rebuilding, and running the tests file again.
00:07		lue	or just that one test.
00:07		masak	yeah.
00:07		masak	I tried that here, and it doesn't hang anymore.
00:08		masak	now running all tests, to see what's the next interesting failure.
00:08		lue	got a No Match. At least it didn't hang!
00:09		masak	the `./test-regex 'a**bc' ''` should indeed give 'No match'.
00:09		masak	it's trying to do '' ~~ /a ** b c/
00:13			dual joined #perl6
00:16		lue	how's it going masak?
00:16		masak	running the tests :) still not past 414. just passed 200, though.
00:17		masak	whoa! Segmentation fault
00:17		masak	that's been a while.
00:17		diakopter	ltns, sigsegv
00:18		lue	GPF (can you guess what it means _here_?)
00:18		masak	the regex in question runs fine in isolation, so the segfault is due to general Parrot weariness.
00:18		* masak	tries the test suite again
00:19		masak	getting to be time for me to hit the pods, too.
00:19		lue	You have an ex-parrot!?
00:19		masak	seems I do.
00:20		masak	but on average, Parrot is much less dead nowadays than a year or two ago.
00:21		lue	Then 2 things are true about you.
00:21			dual_ joined #perl6
00:22		lue	1) You don't have a Norweigan Blue
00:22		lue	2) You didn't get it in Bolton
00:22		masak	I find no fault in that logic.
00:24		lue	Corrolary to 2) You didn't get it in Notlob
00:24		lue	.mmorpg(The expansive bed chamber of RD* is ready to receive occupants)
00:25		* masak	yawns
00:26		masak	just going to see if I can reproduce this segfault, and then go to bed.
00:26		masak	if it persists, probably the way to run the other tests is to change the order in which the files are run.
00:27		lue	So, today on my P6 checklist is a) begin a P6 created general-purpose utility for dealing with DNA/RNA
00:27		lue	b)design the layout of the rakudo death star
00:27		masak	'dealing with'?
00:27		masak	do you mean handling transcription/translation and their inverse operations?
00:28		lue	"decoding/encoding" it, analysis, maybe even a Life Simulator (in the distant future of course)
00:28		masak	hm, translation is proteins.
00:28		Tene	'night masak
00:28		masak	Tene: 'night. if you're here during the weekend, I'll be happy to meet to discuss the Last Mile of Web.pm.
00:28		lue	It's scary how DNA, out of all organic matter and processes, relates to programming. (IMO)
00:28		masak	aye. DNA is digital.
00:29		Tene	lue: http://www.guardian.co.uk/scie[…]nthetic-life-form
00:29		masak	huh. this time, it didn't segfault. that's both good and bad news.
00:29		Tene	masak: Yes, that would be great.
00:29		lue	Tene: I know. It kills me
00:30		lue	The Dark Side now can patent the Creation of Life
00:30		masak	don't worry. I'm sure there's Prior Art.
00:30		lue	c) Profit!
00:30		lue	masak: the USPTO tends to patent discoveries. I'm scared.
00:32		lue	Although, he does prove now that I could throw nucleotides into the proverbial blender and by chance make a TARDIS :D
00:32		masak	it is in times like this that I would advice not forgetting to breathe properly.
00:33		lue	*gurk*
00:33			dual joined #perl6
00:33		masak	throwing nucleotides into the proverbial blender is half of how evolution works, so I can't claim the idea doesn't have some merit...
00:35		lue	or, if you want to have a chance, change the Hox Genes, and change the proteins for brain-building into producing cells of Si (yada yada yada)
00:38		masak	yay, the tests now run past 415. \o/
00:38		lue	\o/
00:40		masak	test 440 fails.
00:40		masak	that'll be tomorrows riddle to crack.
00:41		masak	s/ws/w's/

08:34		moritz_	spinclad: well, it's TimToady's decree that everything should be usable like a List
08:37		spinclad	right.  singleton lists == their singlething.  well, it doesn't DW_I_M, but it is well entrenched by now.
08:37		moritz_	I must confess I also feel a bit uneasy at the notion
08:38		spinclad	so yes, 3[1] would be Nil to mark EOL.
08:39		spinclad	(or is that only if you actually iterate it?  dang, i'll have synopsize on it again.)
08:39		moritz_	problem is, it's probably not in any synopsis, but an uttering here in IRC

11:00		masak	and I'm not sure I know how to argue for one model or the other.
11:00		moritz_	is there something like "best practise"
11:00		moritz_	if somebody else tracks my branches, giving them new names every few weeks is certainly confusing
11:01		masak	apart from "don't push/rebase/push", I don't know.

11:47		isBEKaml	is that a private sub in there?
11:48		colomon	isBEKaml: it's defined in Array.pir, I believe.  Or possibly Seq.pir
11:48			pmurias joined #perl6
11:48		isBEKaml	colomon: I'm looking at Seq.pir, since I don't find it in Array.pir
11:48		pmurias	diakopter: hi

11:49			[Coke] joined #perl6
11:50		isBEKaml	colomon: aye, sir. but I don't have ack, I use find and fgrep. :)
11:56		isBEKaml	colomon: the problem is, even if I do find the sub/method, I won't know how that's related to what I'm looking for. For instance, I didn't know that Array is a Sequence. :)
11:56		colomon	:)
11:57		pmurias	masak: looking at your slides do you claim that if (my $foo = 42) {...} is an example of a bug sigmund finds
11:57		colomon	isBEKaml: I believe Seq is on the chopping block at the moment, too.
11:57		pmurias	masak: if $a = 42 {...}
11:58		isBEKaml	colomon: I don't understand. Chopping block? You mean, it will be dropped?
11:58		masak	pmurias: yes. it'd probably not merit a note on the error level, but on the warning level.
11:59		masak	because in some rare cases it might be what the programmer intended.
11:59		colomon	isBEKaml: there is supposed to be a major rewrite of list/Seq/Array in the very near future, and it seems most of us hate Seq.
12:00		masak	colomon: what are the reasons for hating Seq? I don't think I've had much exposure to it.
12:00		masak	but I definitely think there is an undue proliferation of almost-similar types in that area.
12:00		isBEKaml	colomon: Oh, I see...
12:03		colomon	masak: give me a moment, trying to finish a blog post before I have to take on the morning duties of a dad.
12:03		masak	oh, no rush.
12:03		mathw	Hey
12:06		pmurias	masak: if my $a = 42 {...} is a thing i use regularly
12:08		isBEKaml	masak: I have made that mistake before and I force myself a re-look every time I write code. I still make mistakes.
12:08		masak	pmurias: even with the RHS being a literal?
12:08		masak	isBEKaml: me too.
12:08		pmurias	masak: literal no
12:09		masak	pmurias: that's mainly the case I'm talking about.
12:09		isBEKaml	masak: I keep forgetting that p6 doesn't need parens around if blocks, parens help even if that's a practice from elsewhere. :)
12:09		pmurias	if'ing for an literal doesn't seem very sensible
12:10		masak	pmurias: well, hence the high probability of a thinko.
12:10		slavik	how can I make an iterator for a list?
12:10		colomon	loliblogged: http://justrakudoit.wordpress.[…]ing-two-numerics/
12:10		isBEKaml	masak: if ( my $a == 42)  # I prolly won't make that mistake if we need parens here..
12:10		slavik	is it: $blah <== @list ?
12:10		masak	pmurias: I sense some slight talking at cross purposes here. you do realize that sigmung finds possible thinkos?
12:11		isBEKaml	masak: OTOH, using if as a postconditional does make me go off.  say 'blah' if my $a = 42; ;0
12:11		masak	isBEKaml: not sure what you mean. why would requiring parens help you not make a mistake? and what mistake are you referring to? using 'my' in the if statement?
12:12		isBEKaml	masak: I was referring to '=' and '==' thinkos errors.
12:12		pmurias	masak: using my in a if statement doesn't seem to be that likely a mistake
12:13		masak	pmurias: indeed. but I only need to use 'my' there when I'm testing for definedness. otherwise I tend to use '->'.
12:13		isBEKaml	masak: Now I see you were referring to the 'my' in an if conditional. Now that doesn't make sense to me.
12:14		masak	isBEKaml: more cross purposes. this conversation needs to slow down a bit. :)
12:14		masak	maybe we should talk in full sentences via nopaste instead.
12:14		isBEKaml	:)
12:15		isBEKaml	masak: maybe, we just found another error here. ;)
12:15		pmurias	masak: so sigmund is intendend to be a "check for the suspisious stuff" debugging aid rather than a Devel::Critic for Perl6
12:15		masak	pmurias: yeah.
12:15		masak	granted, it could evolve into a Critic too.
12:15		pmurias	* Perl::Critic
12:16		masak	but it was born out of the need to find stupid thinko stuff early.
12:16		pmurias	it seems like something that could benefit very much from editor/ide integration
12:16		masak	I started making a list over a year ago of things that would be trivial or easy to catch, using only the parse tree or a slghtly higher-level AST.
12:16		masak	pmurias: yes. I'll explicitly leave that to someone else, though. the Padre people, maybe.
12:17		masak	I'll try to make such integration easy, of course. but I think that would detract too much from what I want to be working on, and probably someone else would wnjoy it more anyway.
12:17		pmurias	masak: you are an emacs user?
12:18		masak	aye. and a vim user.
12:18		masak	I also use Perl 5, Perl 6, Python and Ruby. :)
12:19		pmurias	masak: you use viper?
12:19		masak	no.
12:19		masak	I tend to avoid hybrids.
12:19		isBEKaml	masak: if you're an emacs user, you could write up a plugin for that using elisp?
12:19		masak	perhaps.
12:19		isBEKaml	I don't use emacs, so I don't know. (vim user)
12:19		masak	well, it's certainly possible.
12:20		masak	I'm still not terribly good at Elisp.
12:20		masak	and I don't use Emacs for programming much.

12:30		masak	isBEKaml: I'll be happy to set you straight, though.
12:30		isBEKaml	masak: I'm always confused. ;)
12:31		masak	isBEKaml++ # excellent starting point
12:31		isBEKaml	masak: Range first, Int second, Range again. # I don't know about twigils
12:31		masak	isBEKaml: ok, so. in for loops, you'll be most likely to see `for ^$variable { ... }`
12:31		masak	that's the range you're talking about. $variable is numified and used as the exclusive-upper point of a range starting at 0.
12:32		masak	TimToady referred to prefix:<^> as 'upto' the other day.
12:32		masak	a 'twigil', or a 'secondary sigil' is something that comes after a sigil (one of $ @ % & ::)
12:33		masak	twigils usually denote different scoping of some kind.
12:33		masak	for example $!attr and $.meth denote object has-scoping.
12:33		masak	and $*contextual denote some dynamic scoping.
12:33		slavik	$.meth makes no sense ... $.makemeth on the other hand ... does
12:34		slavik	:)
12:35		masak	isBEKaml: so ^$var creates a range, whereas $^var denotes a variable which also is an auto-declared positional parameter in a sigil-less block.
12:35		masak	isBEKaml: a bit like `sort { $a <=> $b }` in Perl 5.
12:36		masak	isBEKaml: in Perl 6, you'd write `sort { $^a <=> $^b }`, which is sugar for `sort -> $a, $b { $a <=> $b }`
12:36		masak	i.e. a block with two parameters $a and $b. but with $^a and $^b, you don't have to declare them as such.
12:37		isBEKaml	masak: yeah, I tried -> this morning.closures.
12:37		masak	now, it's CONCEIVABLE that one sometimes means `for $^range { ... }` in code, but it'd have to be very rare.
12:37		masak	most likely it's a typo for `for ^$range { ... }`

12:44		isBEKaml	twigils can bind themselves to anything? this looks a lot like closures...
12:44		masak	well, they are closures.
12:44		masak	they bind themselves to the innermost surrounding block.
12:44			BrowserUk joined #perl6
12:45		masak	which is a problem sometimes, because you might want to refer to a further-out surrounding block.
12:45		isBEKaml	masak: AFAIK, closures can bind one local parameter and one free variable. Binding the free variable here is what constitutes a closure. #I might be wrong here...
12:45		masak	which is why $a is a synonym for $^a after the latter has been used once.
12:46		masak	isBEKaml: a closure is simply a block that retains information about its surrounding environment.

12:48		p6eval	rakudo 9a15b8: OUTPUT«23␤0␤»
12:48		masak	here, the closure is { $c++ }. it retains a binding to the $c, declared in the 'iter-gen' sub.
12:48		masak	you could store the closure from several different iter-gen calls into different variables, and they'd all count up their very own $c independently of each other.
12:49		masak	I'd show it, but Rakudo is broken in that area right now, so one needs to manyally pir::clone() to make it really work.
12:49		masak	but anyway, that's closures. they 'close' over a surrounding environment, keeping references to some variables which would otherwise have gone out of scope.
12:50		masak	in many ways, they have the aspects of very light-weight objects.

12:53		isBEKaml	yeah and maybe update the glossary
12:53		masak	the specs are hard to read. I'm currently struggling through what the last section of S04 actually means.
12:55		isBEKaml	masak: Very relevant. "When a closure is not a closure"
12:55		isBEKaml	:)
12:55		masak	yeah. I think I see the intent of that section, but my brain hasn't yet succeeded in enveloping the technical specifics.
12:56		masak	which probably means I should keep chunking up until the concepts are few enough to fit. :)
12:57		masak	(and no, 'chunking up' is not a drug euphemism, it's an NLP term. http://www.renewal.ca/nlp27.htm )
12:57		isBEKaml	that's what this says: ...ever use the current reference to the routine, it gets the current snapshot of its world in terms of the lexical symbols that are visible to it

Eg. my $x=123; sub ($a) thing{ return $a * $x }   ...;   my @a <== map{ thing( $_ ) }, 1 .. 10; That is, the piped map is run in a kthread, it uses thing() which is a first class function, defined in the current kthreads as a closure over $x, which is a lexical defined in the spawning kthread.

13:23		masak	BrowserUk: what helps most is if you air your disconcertedness in the form of questions here on-channel.
13:23			protorom joined #perl6
13:23		masak	some types of lack of definitiveness are actually the Sxx documents just being scattered due to the way they were written.
13:24		masak	some things are indeed inconsistent, contradictory or not-specified-enough. we're always on the lookout for those things.
13:24		masak	S09 was brought up as something the other day that'll probably undergo review as soon as someone starts implementing it.
13:25		masak	also, S06 and S19 are known to contradict each other a bit.
13:25		pmichaud	some things are not-definitive because we really need an implementation to work before we can be definite
13:29		BrowserUk	masak: It's quite hard to put into words with specific examples. I've been reading SO9 over and over, and there seem to be a lot of "maybe"s and "or shoudl it be?"s and "somehow"s ... more generally, just a lack of "this is how it will work".
13:30		masak	BrowserUk: nod.
13:30		masak	BrowserUk: what would be really useful, but will probably be quite hard, is if someone wrote "real code" on the current S09.
13:30		masak	to sort of shake out the uncertainties.
13:30		colomon	jnthn: (backlogging) Seems like once or twice a day I try to tab-complete a normal (but long) word here.  :)
13:31		masak	the problem with that, of course, is that there's nowhere to run that code right now.
13:31		BrowserUk	I understand the reasoning for them starting out that way, but ... without joining any bandwagons... it feels like it should be somewhat more defined by now.
13:32		BrowserUk	I'm guessing (hoping) that SO9 is probably one of the worst in this respect due to the nature of what it covers.
13:34		isBEKaml	colomon: I was surprised to find my name in the release notes to Erlangen in your blog... What did I do wrong? ;)
13:34			redicaps joined #perl6
13:35		BrowserUk	Normally, with less ambitious projects, you either define them in terms of what is known to be possible--and then implement. Or define what is required and then work out how to implement. BUt here both ends are speculating upon what the other will want/will be able to do. That makes progress from either end hard to reason about.
13:35		masak	BrowserUk: IO (S16) is still weak. concurrency (S07) is weak. command line options (S19) are weak. Pod (S26) is weak. there are a couple of fairly solid synopses, notably S02, S03, S04, S05, S06 and S12.
13:36		isBEKaml	Those solid synopses are what I'm trying to read, unsuccessfully, over the past couple of weeks...
13:37		* isBEKaml	thinks maybe he will get it in, one day... #just waits for the epiphany moment... ;)
13:37		* BrowserUk	doesn't have the requisite savvy for most of those, hence trying to stay out of them and stick to something I know a little about.
13:37		masak	isBEKaml: what really helped for me was to use Rakudo and actually write stuff.
13:39		isBEKaml	masak: I am, too. Trying to get existing examples in pugs repo working with Rakudo. Since, we no longer use pugs, I guess we're okay with porting them to rakudo.
13:39		masak	isBEKaml: yes, that sounds like a worthy idea.
13:40		isBEKaml	I have just temporarily put an hold on that pursuit until I gain more into S02 until S04...
13:42		isBEKaml	You see, coding up those in confused state is the last thing we all want... :)
13:42		pmichaud	S08 is wrong.  :-)
13:42		isBEKaml	pmichaud++ ## he's definite, here.. :-)
13:44		BrowserUk	maasak: with regard to writing real code. I've been trying. By utilising another language with sufficient existing working code to give a firm underpinning upon which to try things out. I even posted some Perl 5 code that emulated ruoso's test example, but it got no reaction at all.
13:45		masak	BrowserUk: sorry you feel you've been overlooked. I for one am excited to see discussion flowing on the concurrency topic, even if I'm too inexperienced to contribute any to it myself.
13:46		BrowserUk	I'm playing with Erlang because it has both types of threading and a flexible syntax to allow me to "mock up" scenarios, but it slow going--the Erlang manuals are thorough, but tough to find your way around.
13:47		masak	heh. I installed Erlang today, and plan to play around with it a little in my copious spare time.
13:47		* BrowserUk	doesn't feel "overlooked", just walking on eggshells most of the time.

17:14		snarkyboojum	rokoteko: nope - not that I know of anyway
17:15		snarkyboojum	take(5, some list), will return 5 and then the list
17:16		rokoteko	so how is one supposed to refer to the first 5 elements of an infinite list if perl6 provide lazy evaluation?

17:25		TimToady	it's just method call, not function compositoin

17:26		rokoteko	+way
17:26		TimToady	well, there's probably some way to curry it
17:26		TimToady	hmm
17:27		rokoteko	currying more than once is what I missed in perl5 :)
17:27		TimToady	rakudo: my $x = *.batch(5); say $x(1...*)

17:27		TimToady	there's one way
17:27		rokoteko	what is *?
17:27		TimToady	it's a "DON'T curry this argument"
17:27		rokoteko	refers to the last result?
17:28		TimToady	so *.batch(5) really means { $^arg.batch(5) }
17:28		TimToady	or -> $arg { $arg.batch(5) } in a more lambdaish notation
17:28		rokoteko	TimToady: Im not a haskell programmer :)

17:29		TimToady	but yeah, everyone is coming from a different background

17:29		TimToady	in the hopes that one will stick
17:29		rokoteko	well, Im planning to be, but it just for the cause of understanding something different from imperiative languages.
17:30		TimToady	what is your background?

19:12		moritz_	mixing syntaxes considered harmful
19:13		diakopter	which were mixed?
19:13		diakopter	oh, parametric roles syntax for parametric types
19:13		pmurias	patametric roles vs templates
19:13		moritz_	C++ templates
19:13		pmurias	C++ considered evil
19:13		diakopter	that's just C#
19:13		diakopter	different from C++ templates
19:14		moritz_	C# cripped it from C++
19:14		mathw	C# generics are rather different to C++ templates
19:14		diakopter	(ditto)
19:14		* moritz_	talked only about the syntax
19:14		diakopter	but still, p6 doesn't have parametric/generic classes (booo)
19:15		pmurias	it has parametric roles
19:15		diakopter	right, but that doesn't help :P since perlesque won't have roles
19:15		diakopter	too complex for that layer.
19:16		pmurias	perlesque shouldn't even have syntax
19:16		diakopter	?
19:16		diakopter	it shouldn't be a language?
19:17		pmurias	IMHO it should accept AST in JSON
19:17		diakopter	I thought we talked through this and you agreed that was impossible?
19:18		diakopter	besides, how would it translate anything?
19:19		diakopter	who will write the "translate this type of AST node to this" translation routines
19:20		diakopter	show me [an example of or the spec of] the AST API the JSON would match against
19:20		diakopter	VAST?
19:21		diakopter	if it's VAST, that's nowhere close to low-level enough to translate trivially to CIL.

21:20		jnthn	moritz_: oh
21:20		jnthn	moritz_: Actually, that's not the case, I don't think
21:20		jnthn	(more)
21:20		moritz_	or am I doing something execptionally stupid there?
21:20		jnthn	Parrot has fallbacks for set_pmc_keyed_int and set_pmc_keyed_str. If they don't exist, it tries to box the arguemnt and delegate to set_pmc_keyed. And that then throws the error.
21:21			dual joined #perl6
21:21		jnthn	So it almost certainly is calling set_pmc_keyed_int first, it's just that Parrot "helpfully" tires to delegate to set_pmc_keyed
21:21		jnthn	See src/pmc/default.pmc - I get it's in there.

22:46		jnthn	spectesting.
22:50		ajs	rakudo: my @a = <1 2 3>;my @b = @a, <4 5 6>; say @b.perl
22:50		p6eval	rakudo 1499f2: OUTPUT«["1", "2", "3", "4", "5", "6"]␤»
22:51		ajs	That's perfectly sane
22:51		ajs	grr... something is off
22:52			meteorjay joined #perl6
22:52		ajs	In my code I "return @a, <host>" and get [[@a], 'host']
22:53		isBEKaml	ajs: looks like you haven't interpolated your variables.
22:54		ajs	interpolated in what sense?
22:54		isBEKaml	rakudo: my @a=<1 2 3>; my @b = @a, <4 5 7>; say "@b"; #this..
22:54		p6eval	rakudo 1499f2: OUTPUT«@b␤»
22:54		isBEKaml	rakudo: my @a=<1 2 3>; my @b = @a, <4 5 7>; say @b[]; #this..
22:54		p6eval	rakudo 1499f2: OUTPUT«123457␤»
22:54		isBEKaml	rakudo: my @a=<1 2 3>; my @b = @a, <4 5 7>; say "@b[]"; #this..
22:54		p6eval	rakudo 1499f2: OUTPUT«1 2 3 4 5 7␤»
22:54		isBEKaml	see the quotes there.. :)
22:54		ajs	Oh, sorry. I was shorthanding...
22:56		ajs	I get [[1,2,3],4] from @a=(1,2,3) when I "return @a, 4" or "my @b = @a, 4" or whatever.
22:56		ajs	No, no I figured it out!
22:57		ajs	silly me
22:57		isBEKaml	:)
22:58		jnthn	ajs: It'll not flatten at the point of return, but it should flatten if you put it in list context.
22:58		jnthn	ajs: It returns a Parcel, fwiw.
22:58		ajs	yeah, my @a contained a list of lists
22:58		jnthn	Parcels themselves maintain structure until something makes 'em not
22:58		jnthn	Ah, OK. :-)
22:58		jnthn	That'd do it too ;-)
22:58		ajs	yep ;-)

23:07		bkeeler	Heya lue
23:13		dalek	rakudo: 5cb546e | jonathan++ |  (2 files):
23:13		dalek	rakudo: Make sure that since we build meta-ops once globally, we install them at the top
23:13		dalek	rakudo: of the tree, otherwise we get nasty problems. This uncovered a bootstrapping
23:13		dalek	rakudo: issue, so done a little re-ordering.
23:13		dalek	rakudo: review: http://github.com/rakudo/rakud[…]5e7bc27610588bd8d
23:23		lue	Just curious: If i went insane and tried to convert a .pir file (say in src/builtins) to its equivalent .pm file, would it work/be ok?
23:23		bkeeler	bacek: I think the issue is NQP trying proto regexes in a different order.  Enabling parse tracing helps a lot
23:23		bkeeler	bacek: http://nopaste.snit.ch/20623
23:23		lue	[assuming, of course, everything is done right: changing the makefile appropriately, etc.]
23:24		bacek	bkeeler, yes, I suspected it. Any ideas how to fix it?
23:24		bkeeler	bacek: I generated parse traces with --hash-seed=2 and =3 and compared them
23:24		ajs	rakudo: sub a { return [ <1 2 3>, <4 5 6> ] }; for a() -> $x { say "List: $x" }
23:24		p6eval	rakudo 1499f2: OUTPUT«List: 1 2 3 4 5 6␤»
23:24		ajs	did I miss something there? Shouldn't that be List: [1, 2, 3] and List: [4, 5, 6]?
23:25		bkeeler	bacek: Possibly your grammar is commiting to an alternative that it shouldn't.  I don't have more time right now, but I might be able to look at it more tomorrow
23:25		bacek	bkeeler, thanks a lot!
23:26		bkeeler	Anyway, I'm out for the evening.  See y'all anon
23:26		ajs	ciao bkeeler
23:28		jnthn	ajs: BTW, 5cb546e fixed that bug you mentioned earlier.
23:28		jnthn	(the one with the reduction ops)
