strict will save your sanity in the long run. It will help you with things like redeclaring variables and such ... And for -T look here I know these things will seem like a pain at first but hopefully you'll thank me in the end? :)	[reply]

When strict rules are in effect, any global symbol must be accounted for. This helps find many typo problems, as well as accidental variable sharing. In almost all cases, before the first use of any given variable, declare the variable with a `my $foo;` or `my @blah;`. -- `[ e d @ h a l l e y . c c ]`	[reply] [d/l] [select]
