When I first starting writing Perl, I wouldn't have recognized good Perl code if it bit me on the butt. But experience, and lurking around the Monastery, have at least helped me to recognize the better practices, even if I'm not there myself. It's a bit like sitting in a plane before take-off. Everything in the distance seems a single horizontal line, but as you climb you realize the depth and complexity of what lies beyond.
