The Little MLer is a fun little book, and just as applicable to Haskell as it is to OCaml or ML. However, there are some syntax differences between the type declarations of these two families of languages, and if you're not familiar with OCaml or ML, dealing with these can get in the way of the learning experience. If that's the case, you may find useful my translation of the code examples from that book into Haskell. You can have a look at it here: LittleHaskeller.lhs.
