Operation precedence in Haskell is hard to get used to, but it leads to very clean code after you get used. Try:

  sum . map (\x -> x * x) . filter odd $ [1..10]

Function composition leads to a very stable right-to-left syntax. It also takes some practice, but in Haskell you almost never have to go hunting for operators or remember if something is infix or prefix (except for the shameful single argument '-', as in '-1').
