Module type `Monad.S_without_syntax`

type 'a t

include Base__.Monad_intf.Infix with type 'a t := 'a t

val (>>=) : 'a t -> ('a -> 'b t) -> 'b t: t >>= f returns a computation that sequences the computations represented by two monad elements. The resulting computation first does t to yield a value v, and then runs the computation returned by f v.

val (>>|) : 'a t -> ('a -> 'b) -> 'b t: t >>| f is t >>= (fun a -> return (f a)).

module Monad_infix : sig ... end

val bind : 'a t -> f:('a -> 'b t) -> 'b t: bind t ~f = t >>= f

val return : 'a -> 'a t: return v returns the (trivial) computation that returns v.

val map : 'a t -> f:('a -> 'b) -> 'b t: map t ~f is t >>| f.

val join : 'a t t -> 'a t: join t is t >>= (fun t' -> t').

val ignore_m : 'a t -> unit t: ignore_m t is map t ~f:(fun _ -> ()). ignore_m used to be called ignore, but we decided that was a bad name, because it shadowed the widely used Caml.ignore. Some monads still do let ignore = ignore_m for historical reasons.

val all : 'a t list -> 'a list t
val all_unit : unit t list -> unit t: Like all, but ensures that every monadic value in the list produces a unit value, all of which are discarded rather than being collected into a list.
