This sounds so deeply unwise. Isn't it better to fix warnings when they
arise? While Perl sometimes does add new warnings, they're typically for
code that was already dubious and should be fixed or clarified. One
warning that turns out to have been a mistake is not a reason to turn
off warnings altogether.

No, it was because Larry Wall's design called for 'use 1.2.3' and 'use
Module 1.2.3' to be the standard form and to work without warnings.

Although it's a little annoying for testing users in the meantime, I
think you should simply wait for perl 5.8.2 to reach testing and then
close these bugs. I would far prefer it if -w were on by default, as in
the long run it produces better code. I believe this will be in the case
in perl6.
