I'm sure this is what Richard meant, but to shut off warnings you need
to have a line like

  no warnings;

in your code (not "use warnings;"). Also, I would recommend against
playing with $^W unless you know what you're doing... it only modifies
the value of $^W at runtime, so it won't catch warnings that are usually
raised at compile time.

I think the general consensus I got from the Perlmonks
(http://www.perlmonks.com and #perl on openprojects.net -- thanks, wog)
is that it's better to do 'use warnings' or 'no warnings' to toggle
warnings when using a version of Perl that supports the warnings pragma.
