02:05 idiosyncrat Demat!
02:05 idiosyncrat Lately I've had some fun coding Marpa::R3
02:06 idiosyncrat Lua has powerful, fast coroutines.
02:07 idiosyncrat This is great for Marpa/Kollos, because there are lots of producer/consumer situations, which can be painful to code without coroutines, but which are very easy to code with them.
02:08 idiosyncrat Lua also makes it easy to turn coroutines into iterators, so that a complex iteration can be turned to an iteration and easily reused.
02:10 idiosyncrat Producer/consumer issues can also be dealt with using callbacks and/or flags, but callbacks are not as convenient or elegant, and solving the problem with flags and goto's turns the code into a rat's nest.
02:12 idiosyncrat Very helpful in coding reusable coroutine-based iterators, is the Lua (like Perl) allows closures, so that an iterator can easily keep state between iterations.
02:44 ronsavage JK: Re: http://irclog.perlgeek.de/marpa/2017-05-18#i_14598828. Should the final 'iteration' be 'coroutine' in that sentence?
02:51 idiosyncrat Lua also makes it easy to turn coroutines into iterators, so that a complex iteration can be written up using coroutines, turned to an *ITERATOR* and, thereafter, easily reused.
02:52 idiosyncrat ronsavage: Thanks.  The above revises and extends that sentence for clarity.
