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

l >|= f is the infix version of map with reversed arguments.

val (@) : 'a t -> 'a t -> 'a t

l1 @ l2 concatenates two lists l1 and l2. As append.

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

funs <*> l is product (fun f x -> f x) funs l.

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

f <$> l is like map.

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

l >>= f is flat_map f l.

val (--) : int -> int -> int t

i -- j is the infix alias for range. Bounds included.

val (--^) : int -> int -> int t

i --^ j is the infix alias for range'. Second bound j excluded.

val let+ : 'a t -> ('a -> 'b) -> 'b t
val and+ : 'a t -> 'b t -> ('a * 'b) t
val let* : 'a t -> ('a -> 'b t) -> 'b t
val and* : 'a t -> 'b t -> ('a * 'b) t
val and& : 'a list -> 'b list -> ('a * 'b) list

(and&) is combine_shortest. It allows to perform a synchronized product between two lists, stopping gently at the shortest. Usable both with let+ and let*.

# let f xs ys zs =
    let+ x = xs
    and& y = ys
    and& z = zs in
    x + y + z;;
val f : int list -> int list -> int list -> int list = <fun>
# f [1;2] [5;6;7] [10;10];;
- : int list = [16; 18]
