dmckee has asked for the wisdom of the Perl Monks concerning the following question:

It is stated in the book of man perl
Thou shalt use perl -w before moaning about Perl.

However, I'm using Windows, so it's trickier to run -w, and I can't use the #!perl -w trick except under Apache. Are there any reasons why the use of 'use warnings' appears to be depreciated? (Naturally, I bung it in at the top of my code, along with 'use strict')
