After further discussion at today's PSC meeting, we decided this warning should be under the `experimental::` space, because the behaviour of @_ inside a signatured sub is really the one thing that remains experimental about signatures (besides all the new features we intend to add, but they can be added independently). I've therefore changed the warning category to the cute-but-nonobvious no warnings 'experimental::snail_in_signatures'; I'm not sure this name is very clear for users to read or discover, but I couldn't think of anything else sufficiently snappy and short. If anyone has any better suggestions I'll consider them. In the meantime, since the old PR was getting full of old junk and in any case github doesn't let you rename the branch of a currently-open PR, I closed it and opened a brand new one: https://github.com/Perl/perl5/pull/19377 -- Paul "LeoNerd" Evans leonerd@leonerd.org.uk | https://metacpan.org/author/PEVANS http://www.leonerd.org.uk/ | https://www.tindie.com/stores/leonerd/Thread Previous | Thread Next
