I learned Perl internals basically by subscribing to perl5-porters, reading most of the traffic, and reading the patches. By reading the patches and the descriptions of what they did, I was able to get a feel for where theings were in the core. Next, I did a couple small projects. Once I felt comfortable with the core, I picked something I wanted to implement and did it.
