[Ocaml-lib-devel] Enum.iter2

[Alan P. <ap...@re...>]

Is there a reason why Enum.iter2 does index stuff?  Currently the
implementation is:

let iter2 f t u =
        let rec loop idx =
                f (t.next()) (u.next());
                loop (idx + 1)
        in
        try
                loop 0
        with
                No_more_elements -> ()


Why not:

let iter2 f t u =
        let rec loop () =
                f (t.next()) (u.next());
                loop ()
        in
        try
                loop ()
        with
                No_more_elements -> ()
