Note that "currying" applies to operator sections too. The idiom of "pipelined functions" deserves its own special mention:

countlines = length . lines

But this is really a shorthand for:

countlines cs = length . lines $ cs

an interesting use of $ (in conjunction with another infix). I usually write: countlines cs = length $ lines cs or more general f = g . h . i becomes f x = g $ h $ i x Christian
