One of the other links that google found with that piece of code in it was a pdf document (I think it is in Italian).

Though I'm not Italian either, it's certainly in Italian and seems to be written by Zack, one of the good guys, a PhD student at the University of Bologna and a big fan of open source software, especially Debian, OCaml, Python and Perl. Maybe he's a Perl monk? Any Italian monks know him?

I suppose you could send him a nice email (in Italian of course;-) thanking him for including your code, but suggesting a more specific reference, i.e. instead of just www.perlmonks.org to use www.perlmonks.org/?node_id=423988. It's up to you, of course, but I probably wouldn't bother. OTOH, it might work out well and you might make a new friend or even persuade him to join the monastery...

Ciao!
