Thanks for the link. I'm a self-taught coder of about 13 years now (C, Java, Ruby) and I always feel like there's a few basics I'm missing so I'll probably tackle this after Lisp. Besides, Python has always seemed like a very nice syntax (love when indenting means something but the colon bugs me).
This looks like a great book, I perused it briefly a while back, but I think that if you've been coding for 13 years you're well beyond the level of its target audience.
