18:32 Igloo Is there a simple example of where PQ commutes but QP doesn't?
18:41 Igloo Oh, I think it's easy to make one with hunk patches, actually
18:44 Igloo Hmm, maybe not
18:45 * Igloo has an example with replace patches, but I'd rather not mention them
18:49 arjanb hunk 0 [a,b,c] -> [x] ; hunk 2 [c] -> []
18:50 Igloo That doesn't commute either way round, does it?
18:51 Igloo In fact, I'm pretty sure it isn't possible with hunks, due to the symmetry of the commute conditions
18:51 Igloo And I can't see how it could be possible with file moving etc either
18:52 Igloo So I guess it'll have to be replace patches
18:52 arjanb it commutes to hunk 4 [c] -> [] ; hunk 0 [a,b,c] -> [x]
18:53 Igloo Oh, silly me
18:53 Igloo Thanks!
