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.

t >>| f is t >>= (fun a -> return (f a)).

bind t ~f = t >>= f

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

map t ~f is t >>| f.

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

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.

These are convenient to have in scope when programming with a monad:
