And thus, by my definition, you're not "into" Perl, in the way that I would look for if I were hiring a Perl hacker to work for me.
There's nothing wrong with that. This discussion started by trying to sort out why "PERL" is bad on a resume. It's a red flag for me, because it means you're not "into Perl". I probably wouldn't even return that guy's call.
I'm not sure why people are freaking out about this. It's about respect of the culture, which I consider an essential component for being a good Perl programmer.
