Hello Dhaemon,

because most complex parts of code are really functional and Haskell give ability to express them shortly and reliably

Also, in many ways haskell is a 'better impertive language than imperative ones'. the ability to treat IO actions as values and build up computations functionally means your imperative code can end up being much more concise, not to mention typesafe. John

What was that slogan? "Haskell - the finest imperative language in the world"?

yeah, something like that. it was in a paper, 'tackling the akward squad' maybe? I have wondered whether a book explicitly teaching haskell as an advanced imperative language from the beginning, introducing advanced FP and type system concepts slowly, would do well. somewhere in chapter 8 or so it would say "ha! little do you know, but you have been actually learning advanced functional programming for 3 chapters now!"
