I didnt know this when I _started_ :) So, thats why I am learning Haskell

Yes, as someone pointed out, Haskell was meant for a lot of computation,
and IO is just a part of the story!

But, being a computer science student, I think I need to look into it too!
I like the quote found on this site: http://patryshev.com/monad/m-intro.html
Monads in programming seem to be the most mysterious notion of the century.
I find two reasons for this:
* lack of familiarity with category theory;
* many authors carefully bypass any mention of categories.
It's like talking about electricity without using calculus.
Good enough to replace a fuse, not good enough to design an amplifier.

Ah, I am not familiar with the "term-rewrite" you are talking about.
I will Google it up then.
