Module Option.Let_syntax

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

val return : 'a -> 'a option
val (>>=) : 'a option -> ('a -> 'b option) -> 'b option

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 option -> ('a -> 'b) -> 'b option

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