You could say I am someone who knows how to do it...

Given this is an interview question, I'm quite concerned to be honest, especially given your analysis on the future of Perl.

If you are being interviewed and can't answer this, how are you qualified to provide analysis, particularly statistical on the usage of Perl?

What exactly is it you want to know? Are you just looking for someone to give you a syntax answer so we can satisfy the requirement of some dev team director that doesn't know his ass from a hole in the ground? ;) I'll be watching for further responses. For now, I don't have one. I'm sorry.
