val (>|=) : 'a t -> ('a -> 'b) -> 'b t

o >|= f is map f o.

val (>>=) : 'a t -> ('a -> 'b t) -> 'b t

o >>= f is the monadic bind.

val (<*>) : ('a -> 'b) t -> 'a t -> 'b t

f <*> o returns Some (f x) if o is Some x and None if o is None.

val (<$>) : ('a -> 'b) -> 'a t -> 'b t

f <$> o is like map f o.

val (<+>) : 'a t -> 'a t -> 'a t

o1 <+> o2 is o1 if o1 is Some _, o2 if o1 is None.

val (|?>) : 'a -> ('a -> 'a t) -> 'a

x |?> f is apply_or f x
