I would agree, it could be a useful section. FWIW, you can check out Perlguts Illustrated, which is a good read, as well as the start of perlhacktut (I don't think it has yet been completed) or here (this one may be more complete), and there is also the perlguts man page.

Cheers,

Update: The final link pointing to perlhacker.org no longer works. As of this update, you can find that particular article here.
