I'm currently reading Higher-Order Perl by Mark Jason Dominus, which  
is really just a functional programming techniques handbook for  
Perl.  I'm writing about what I'm finding along the way, and  
translating much of the code.  It probably makes a lot more sense if  
you read the book first, but here are the links, in case they help:

I'll have the infinite streams article up soon...
