`include Core_kernel.Monad.Infix with type a t := a t`
`type '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))`.

`val (>>>) : 'a t ‑> ('a ‑> unit) ‑> unit`
