type +'a t
val return : 'a -> 'a t
val (>>=) : 'a t -> ( 'a -> 'b t ) -> 'b t
val (>>) : unit t -> 'a t -> 'a t
val map : ( 'a -> 'b ) -> 'a t -> 'b t
The monadic laws must hold:
(x>>=f)>>=g
x>>=fun x' -> (f x'>>=g)
return a >>= f
f a
x>>=return
x
As well as the following identities:
x >> y
x >>= fun () -> y
map f x
x >>= fun x' -> f x'
