[12​:40​:44] <lizmat> looking at (;;$a) signature
[12​:41​:12] <lizmat> apparently the internal datastructure is set up the same way for (;;$a) as it is for ($a;;)
[12​:43​:23] <lizmat> jnthn​: I'm not sure how to fix that in the grammar
[12​:44​:11] <moritz> ($a;;) should be the same as ($a), no?
[12​:44​:23] <lizmat> yes
[12​:44​:33] <lizmat> but *not* the same as (;;$a)
[12​:45​:17] <lizmat> the ;; just resets the multu-invocant flag to be applied to the parameter
[12​:45​:34] <lizmat> in the case of (;;$a), the reset happens too late
[12​:54​:32] <jnthn> lizmat​: I don't immediately know how to fix that...
[12​:54​:41] <lizmat> me neither :-(
[12​:54​:42] <jnthn> lizmat​: Agree it's a problem, though
[12​:55​:02] <jnthn> Can you RT it, and I'll take a look at it a bit later...
[12​:55​:06] <lizmat> ok, I'll rakudobug it
[12​:55​:10] <jnthn> Thanks :)
