Monad (merlin-lib.merlin-lib.ocaml_utils.Ocaml_utils.Misc

module type Basic2 = sig ... end

Multi parameter monad. The second parameter gets unified across all the computation. This is used to encode monads working on a multi parameter data structure like (('a,'b) result).

module type Basic = sig ... end

module type S2 = sig ... end

module type S = sig ... end

module Make (X : Basic) : S with type 'a t = 'a X.t

module Make2 (X : Basic2) : S2 with type ('a, 'e) t = ('a, 'e) X.t

module Identity : S with type 'a t = 'a

module Option : S with type 'a t = 'a option

module Result : S2 with type ('a, 'e) t = ('a, 'e) result
