Well said. I think a lot of people are drawn to Haskell because the abstractions are so well integrated. I remember reading the Prelude and muttering "wow so true" all the way. But then I got stuck when designing a first program.

OOP to me is not imperative control flow but about managing responsibilities. What does this object know, what can I ask it to do, what does it need for the job? If I look at my program at the level of for-loops I'm lost in the brush. And granted, sometimes I do miss Haskell's expressiveness in the brush.
