Comment(by byorgey):
Nothing is lost by the change (other than requiring a tiny bit more work
on the part of Quasi instances) since all monads are also applicative
functors.
However, I note that (Monad m, Applicative m, Functor m) => ... is
redundant, since Applicative m requires Functor m. Hence only (Monad m,
Applicative m) => ... is needed.
