[Haskell-cafe] more functions to evaluate

[Dan Weston]

Yes. Partially applied, (iterateN n) is a kind of iterate function, but 
(iterateN f) would be some kind of "function converting an integer into 
a function", which is much less useful. I would think that the number of 
iterations would usually depend on the function iterated, not the other 
way around.
