Module `Monad`

Combinators on monadic computations.

module type Def = sig ... end: A definition of monads, each of the combinators is used in the Make functor.

module type ListS = sig ... end: List combinators

module type S = sig ... end

module Make : functor (M : Def) -> S with type +'a t = 'a M.t: Expands the monadic definition to extra combinators.
