"Learning Perl Objects, References and Modules" (aka the wooly llama) is also a good next step after you finish "Learning Perl"- I keep re-reading it (it's fairly short but very dense- or maybe that's me. ;) )

Does EVERYONE get a hankering to do this at some point? If not, what might it be indicative of? Hope you have fun in your quest- what a great reason to learn (perl)!
