Description

The compos operator, inspired by

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

Synopsis

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

Compos

compos :: (Fam phi, HFunctor phi (PF phi)) => (forall ix. phi ix -> ix -> ix) -> phi ix -> ix -> ix Source #

Normal version.

composM :: (Fam phi, HFunctor phi (PF phi), Monad m) => (forall ix. phi ix -> ix -> m ix) -> phi ix -> ix -> m ix Source #

Monadic version of compos.

composA :: (Fam phi, HFunctor phi (PF phi), Applicative a) => (forall ix. phi ix -> ix -> a ix) -> phi ix -> ix -> a ix Source #

Applicative version of compos.
