Reading this page got me to write an arrow version of compose. Don't know if it should be included or not since it isn't a monadic solution.
composeArrow :: [a -> a] -> a -> a
Or maybe this:
composeArrow = foldr ((>>>) . arr) (arr id)
composeArrow :: [a -> a] -> a -> a
composeArrow = foldl ((>>>) . arr) returnA
