in reply to Variable scope in packages.

When you require a script(*.pl), it brings it's variables, subs, and all into your namespace so you can simply access it as %crap. Voila!

NOTE: That if you require a package it will not be the same. It will not be automatically included in your namespace and you would have to make each call explicitly -- Credit goes to Petruchio on the note.

$_.=($=+(6<<1));print(chr(my$a=$_));$^H=$_+$_;$_=$^H; print chr($_-39); # Easy but its ok.
