> My experience is that there are two very different kinds of Haskell programmers: those who really understand the math, like you, and those who treat it as a black box (the "Learn You A Haskell" contingent). I don't think that LYAHFGG treats Haskell as a black box, not for the level that it aims to teach Haskell - it makes it very clear that all functions are curried, emphasizes that a functor should be viewed more as of a "computational context" instead of a "box" (for example function composition), and so on. I've found it to be as precise and vigorous as other tutorials on Haskell, for the level it aims at.
