"Perl 6 Now - The Core Ideas Illustrated of Perl 5" It's sitting on my desk now...it's been competing with Higher Order Perl for my attention, but so far I've found it very interesting. Not having a CS degree, or a lot of experience with anything except Perl 5, some of the concepts I've been following on the Perl 6 Language list have been sort of foreign to me.

It's a kind, gentle introduction to those concepts, with real world examples of using them in Perl 5, along with the best idea of what the Perl 6 syntax will be. So far, it has my recommendation....
