Implementation of while loop

[Abraham Egnor]

While "while" can be implemented in haskell, I would strongly suggest you
look at using the many higher-order functions available (foldl/foldr, map,
filter, etc.) - they're much more in line with the spirit of the language,
and will lend themselves to much clearer expressions once you get the hang
of them.

What sort of thing do you want to do in your while loop?  Is it a pure
processing function, or an IO-related one?
