I disable the warning output, so it looks abit nicer when running the script.

You mean you removed strict and warnings ???

I can't check it where I am right now, but I don't see anything that would cause you problems, unless you're running on a very old or customized Perl.

Perhaps you could relate what warnings you're getting, and we might convince you to put strict and warnings back in? Or perhaps it's related to your larger script, and not to this minimal example?
