I don't think ProjectEuler is very helpful for learning a language. The first ten problems or so might be useful to learn the basic syntax, but after that it's really just about number theory, or optimizing brute force. If you're looking for Haskell beginner exercises, I recommend a) implementing functions from Prelude, Data.List, Data.Tree yourself b) doing the exercises given in RWH (even if you don't actually read the book - just do those you understand).
