how important is 'use warnings' ?

[spookie]

Hi,
As strict pragma is recommended and should be included in perl file, i am wondering if 'use warnings' is as recommended as strict.

Your opinion ?

There are two methods of turning on warnings:

#!/usr/bin/perl -w

or

#!/usr/bin/perl
use warnings;

The second method allows you to temporarily turn off warnings if necessary for parts of your program (similar to the way you can temporarily disable strict checking too).

I always recommend using warnings just like using strict. Again it can require a little more effort in writing your programs to avoid throwing warnings but it does cause you to write better, more robust code as a result. I always enable it for everything other than one-liners.
