I was referring to Robin's mentioning space/time usage, so yes, that's
what I meant.

Actually not. You need advanced knowledge to *avoid* doing IO. (If
higher order functions like map, fold count as advanced.) A good,
readable, maintainable Haskell program is almost completely pure and
does very little IO. Of course you can write an IO-heavy program in the
same style you'd use in C, but it would be exactly as ugly.

You will soon. Once you get used to composing functions instead of
sequencing actions, you'll appreciate the difference.
