To avoid confusion, in gui code you will often see the &somesub syntax, because often gui's will automatically pass the calling widget as it's first argument to the sub, and the & supresses it. Like:
-command=>[\&raiseit,$win]) # passes $win as first arg # instead of widget or event # not a 100% foolproof rule
So, even though the somesub() syntax is preferred ( and most correct), be prepared to see other weird constructs. Everytime I write a sub, I usually put
sub somesub{ print "@_\n"; .... .... }
as it's first line, just to be sure what I'm getting. Sometimes I surprised by what comes in.

I'm not really a human, but I play one on earth CandyGram for Mongo
