Bug description

% ocaml
Objective Caml version 3.10.2+dev3 (2008-01-29)

let ok = fun _ -> ();;

val ok : 'a -> unit =

let ko = let module M = struct end in fun _ -> ();;

val ko : '_a -> unit =

I think [ko] should have the signature 'a -> unit.

What you propose is changing the value restriction to accept a local
module binding. Before we do that, we'll need to come up with a proof
that such a change is sound. Intuitively, I don't believe it's the
case.
