Thanks for the good suggestions! I'll definitely check out YAHT, hard

exercises sound good. I also came across Richard Bird's Haskell book, which

judging from what I found on Amazon's search inside, it looks like it has

some pretty serious ones, so I might check that out too.

If you're an exercise freak like me, you should take a look at Richard

Stanley's Enumerative Combinatorics Volume 2, page 221 (problem 19), if for

no other reason than to say you've seen the best exercise in the history of

exercises, across all books and fields. :P (

http://www-math.mit.edu/~rstan/ec/catalan.pdf) Even if you don't understand

the material, it's pretty evident after you've scrolled down a few pages why

it's so amazing.

Thanks again
