Zero-to-Perl

I have a lot of experience with a lot of programming languages including Perl, and occasionally contribute small things to DW. Don't mind me. There are big chunks of DW (and probably Perl) that I'm not familiar with from everyday use, so I always feel like I'm reverse engineering everything when I try to help. I'm looking to keep up with DW best practices, what we teach our devs, and be able to contribute more than the occasional tiny patch.
