That (a -> m b) in the middle is what's failing to typecheck. The
error is a bit obtuse because ghci is trying hard to find a way to
do what you want, so it assumes "m" is "(-> r)" (the functor/monad
representing functions, also known as the Reader monad)
Ehm? What? I haven't seen the (-> r) monad anywhere near this code.
