Silly spin-offs are also common, leading to such wiki pages as http://haskell.org/haskellwiki/Compose. That particular example was mostly my doing and answers the question 'Can you build a function compose :: [a -> a] -> a -> a, such that a value will be fed into the top of the list and we'll get a result out of the bottom?'. Of course, the sane solution is foldl (flip (.)) id,
flip (foldl (flip id)) ? I usually use the reverse composition, flip (foldr id).
