Module `Monad.Option`

type 'a t = 'a option

include Misc.Stdlib.Monad.S2
  with type ('a, _) t := 'a Misc.Stdlib.Monad.Option.t

val bind : 
  'a Misc.Stdlib.Monad.Option.t ->
  ('a -> 'b Misc.Stdlib.Monad.Option.t) ->
  'b Misc.Stdlib.Monad.Option.t

val (>>=) : 
  'a Misc.Stdlib.Monad.Option.t ->
  ('a -> 'b Misc.Stdlib.Monad.Option.t) ->
  'b Misc.Stdlib.Monad.Option.t

>>= is a synonym for bind

val return : 'a -> 'a Misc.Stdlib.Monad.Option.t

return v returns the (trivial) computation that returns v.

val map : 
  ('a -> 'b) ->
  'a Misc.Stdlib.Monad.Option.t ->
  'b Misc.Stdlib.Monad.Option.t

val join : 
  'a Misc.Stdlib.Monad.Option.t Misc.Stdlib.Monad.Option.t ->
  'a Misc.Stdlib.Monad.Option.t

join t is t >>= (fun t' -> t').

val both : 
  'a Misc.Stdlib.Monad.Option.t ->
  'b Misc.Stdlib.Monad.Option.t ->
  ('a * 'b) Misc.Stdlib.Monad.Option.t

val ignore_m : _ Misc.Stdlib.Monad.Option.t -> unit Misc.Stdlib.Monad.Option.t

ignore_m t is map (fun _ -> ()) t.

val all : 
  'a Misc.Stdlib.Monad.Option.t list ->
  'a list Misc.Stdlib.Monad.Option.t

val all_unit : 
  unit Misc.Stdlib.Monad.Option.t list ->
  unit Misc.Stdlib.Monad.Option.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.
