That largely misses the point. My objection is to the mindset behind the question. > the first bit is very similar to, say, > > counter a = (a, \to_add -> counter (a + to_add)) Which looks to me like imperative programming. Indeed, the Monad answer that I posted is imperative programming, it just happens to be done in Haskell. Stepwise transformation of a state is, on some occasions, the right answer to a problem. Unfortunately in this thread we haven't been told what the problem is. The question is of the form "how do I make a hammer?" when a hammer is rarely the most appropriate tool. That's what I'd like to get away from.
