[Caml-list] module types

[Damien <Damien.Pous@ens-lyon.fr>]

Hi,


module type T = sig type 'a t end
module F(M: T): sig
	type a
	type t = a M.t
	(* plus a lot of values... *)
end = struct
	type a = unit
	type t = unit M.t
end

I would like to re-write it like this :

module type T = sig type 'a t end
module type O = 
sig 
	type a 
	type t 
	(* plus a lot of values... *)
end
module F(M: T): O with type t = a M.t =
struct
	type a = unit
	type t = unit M.t
end

but I can't, because "a" is unknown...
(of course, I want to keep it abstract)

any idea ?

thanks,
damien
