Re[2]: [Haskell-cafe] Is this haskelly enough?

DFP> Yes, but that generality is entirely wasted here and thus an DFP> obscuring element. There is no way that this function can be DFP> generalized to work with other monads. As for me, concatMap (and concat.map as well) seems much more obscuring. (>>=) is so general, that I use it almost everywhere, but I have to dig into my memory to remember concatMap (or is it mapConcat?)
