val (>>=) : 'a t -> ('a -> 'b t) -> 'b ta >>= f is the infix version of flat_map.
val (>>|) : 'a t -> ('a -> 'b) -> 'b ta >>| f is the infix version of map.
val (>|=) : 'a t -> ('a -> 'b) -> 'b ta >|= f is the infix version of map.
val (--) : int -> int -> int tx -- y creates an array containing integers in the range x .. y. Bounds included.
val (--^) : int -> int -> int tx --^ y creates an array containing integers in the range x .. y. Right bound excluded.
