[Caml-list] Is this a bug?

[John Max Skaller <skaller@ozemail.com.au>]

There is a bug here: is it in:

 Objective Caml version 3.04+11 (2002-05-16)

or is it in my code:
 
in one module:

    | `TYP_none -> print_endline ("NONE DETECTED");
       0,"Unknown"
 
in another module:

       | `DCL_val t ->
          print_endline ("val " ^ id^ "[old] : " ^ string_of_typecode t);
          let t' = match t with | `TYP_none -> `TYP_var n | _ -> t in
          print_endline ("val " ^ id^"[new] : " ^ string_of_typecode t');

output (2 test cases):

val printv[old] : Unknown
NONE DETECTED
val printv[new] : Unknown
NONE DETECTED
val x[old] : Unknown
NONE DETECTED
val x[new] : Unknown


The code also fails if I replace the match t with |`TYP_none with
and if/then/else construction.

It looks like the constructor `TYP_none isn't equal to itself :-)
