I no longer think all kinds of gateways to Haskell is actually a good thing. Once you go through that gateway you are most likely to get frustrated and go right back, as evident from other replies. People say it's enforced purely functional programming is difficult to grasp but I write mostly pure FP in Scala and I get frustrated with how difficult it is to build something practical in Haskell
