To be clear: (- 2) is not a section in Haskell, it's effectively a numeric literal because '-' is Haskell's only prefix operator. Haskell has a 'subtract' function that's defined in its Prelude that is used where a section for (-) would be useful. It's a minor wart, and probably never going to be fixed. EDIT: clarified
