> And what does strict (Perlicism?) do?

strict enforces declaration of variables before usage. So 

use strict;

makes you issue a

my $variableName;

statement so the if you accidentally type $myVar or $myvariable later on,
an error will occur, rather than a new variable being created. This is
great for code maintainability, especially when you cut and paste functions
from other code.
