What I wanted was for 'use warnings qw(-foo)' to mean the same as plain old 'use warnings' but without 'foo'. If the user says 'use warnings qw(foo -bar)' then that should I think just turn on the 'foo' warning, and turn off the '-bar' warning. If you've already got some warnings turned on but then in some restricted scope want to turn 'foo' warnings off - that's what 'no warnings qw(foo)' is for. So, this: use warnings qw(-foo -bar); would be equivalent to: use warnings qw(all); no warnings qw(foo bar); and this: use warnings qw(foo bar -baz -barf); would be equivalent to: use warnings qw(foo bar); no warnings qw(baz barf); ... and that's what I implemented while waiting for tests to run: https://github.com/Perl/perl5/pull/17500 -- David Cantrell | Hero of the Information AgeThread Previous | Thread Next
