rev_itlist2 : ('a -> 'b -> 'c -> 'c) -> 'a list -> 'b list -> 'c -> 'c

SYNOPSIS
Applies a function to corresponding elements of 2 lists.

KEYWORDS
list.

DESCRIBE
{rev_itlist2 f [x1,...,xn] [y1,...,yn] z} returns

   f xn yn (f xn-1 yn-1 ... (f x1 y1 z)...)

It returns {z} if both lists are empty.

FAILURE
Fails if the two lists are of different lengths, or if an application
of {f} raises an exception.

EXAMPLE

- rev_itlist2 (fn x => fn y => cons (x,y)) [1,2] [3,4] [];
> val it = [(2, 4), (1, 3)] : (int * int) list
