I don't feel it's so clear cut. Haskell fuzzies the difference between syntactic and semantic elements. What in your piece of code is the parentheses might very well be defined as functions in Haskell. For instance, the ($) and (.) functions, but also I would call StateT and perhaps Compose and WrapMonad (while not knowing what they do) such things too. So, I still feel that understanding a piece of Haskell means that you will need to understand the individual functions at least superficially.

You feel wrong. There is no such fuzzy. StateT, Compose and WrapMonad are functions. They are just like foo and bar in my example. Just as in a C-style language you need to know the parens mean function application, in haskell you need to know spaces and ($) are function application, and (.) is function composition. The code is perfectly readable even if you don't know what the functions being used do.
