The compos operator, inspired by

B. Bringert and A. Ranta A pattern for almost compositional functions ICFP 2006

- compos :: (Fam phi, HFunctor phi (PF phi)) => (forall ix. phi ix -> ix -> ix) -> phi ix -> ix -> ix
- composM :: (Fam phi, HFunctor phi (PF phi), Monad m) => (forall ix. phi ix -> ix -> m ix) -> phi ix -> ix -> m ix
- composA :: (Fam phi, HFunctor phi (PF phi), Applicative a) => (forall ix. phi ix -> ix -> a ix) -> phi ix -> ix -> a ix
