I've not been following Haskell too much and am completely lost when reading code like that. I understand (+1), : and ! but what the hell are . and $ for?
Function composition and lowest-precedence function application, respectively.
And that weird monad symbol in the Haskell logo is not even used! >>= Not quite the worst example of such line noise much of Haskell idiomatic code uses nowadays, though.
That's the monadic bind operator. As far as sugar, I think you've got it backwards — the "do" syntax is sugar for >>= and friends. :-)
