Hi, I am a Haskell newbie. Having read some tutorials (Yet Another, Gentle Introduction) and some papers/tutorials on monads, I would like to spend some time practicing what I have learned before embarking on more abstract/obscure things and/or using Haskell for everyday tasks. I am looking for small to medium sized practice problems, preferably with solutions. Hal Daume's tutorial had some good one-liners (eg rewrite something point-free) but I am looking for something which would take 1-3 hours for a newbie, and then I could look at a solution by a Haskell expert and discover what I could have done better/more elegantly. Online references (or even book suggestions) would be appreciated. If you are teaching Haskell and have problems with confidential solution sets (some instructors like it that way), I can promise not to disclose the latter ;-) Thanks, Tamas
