Re^3: Customizing diagnostics?

Well, here's something a bit odd. Here's what I was trying:

$ perl -wce'no warnings "parenthesis"; print ("\n")'
-e syntax OK

Which led me to think that my above reply was correct. If I change no warnings "parenthesis"; to, say, use strict; or chomp; or print "foo";, then the warning comes back. But if I change it to no warnings "y2k"; or even use warnings "y2k" (or any other category from perllexwarn), it stays gone. I'm on 5.8.3.

This is a longstanding bug; using `no warnings "foo"` after `-w` (as opposed to `use warnings;`) disables all warnings; coincidentally, this was fixed a week ago by Rick Delaney and should be better in 5.8.8.	[reply] [d/l] [select]
