Learning the Deeper Secrets of Perl
Advanced Perl Programming is a great book and I guess it will give something to think about for a while.
Anyway the Mastering Algorithms in Perl is more like a guide to use some common (and some that gave me migraine)
algorithms but not really related to the Perl learning itself.
In my opinion you could, by next, (after knowing a lot about Perl and its use with algorithms)
try to apply it in your area of study or work, like networks, AI or admin.
In my case, I'm trying to understand more deeply OO with Perl,Debuggind Perl and
(as a developer working a lot with web these days) the template toolkit and mod_perl related topics.
well... chose your flavor and good luck.
