Because the less power the construct has, the fewer corner cases and generalizations a reader of the code needs to consider. Now, just because iterators exist does not mean that one should never use the more general tool. If you're fighting to break out of your chosen straitjacket, then chances are it's the wrong one to use in the first place; it'd be clearer to use more power and have less fighting.

Note that, as I have already written, I agree with you. And this is one of the reasons i like Haskell. The main problem, here, is that: - recursion and pattern matching are explained in every tutorial about functional programming and Haskell. This is the reason why I find them more "natural". - high level, Haskell specific, abstractions, are *not* explained in normal tutorials or books. The libraries where these concepts are implemented, are not well documented. Most of the "documentation" is in research papers, and a "normal" programmer don't want to read these papers. Only in the recent "Real World Haskell", all these high level abstraction have been properly documented Manlio
