Re: [Haskell-cafe] Functional vs Imperative

Also, just for kicks, may I had this: I read the code of some haskell-made programs and was astonished. Yes! It was clean and all, but there were "do"s everywhere... Why use a function language if you use it as an imperative one?(i.e. most of the apps in http://haskell.org/practice.html)

Note that do expressions are not expressions whose evaluation has side-effects. The evaluation of a do expression doesn't yield the result of the action it describes, causing side-effects, but it yields the action itself. Evaluation of this action is done seperately.

Thanks in advance,
