Interestingly, the Haskell fans that I know happen to be mathematicians by inclination, and programmers because it seems useful. I think you are right that mathematical thinking maps quite naturally onto Haskell. I also think that most programmers are only middling-good mathematicians and aren't the type that enjoys doing air-tight proofs in their spare time as a hobby.
