Subject: include in rec module definition
Date: Mon, 24 Sep 2007 20:05:58 +1000	[thread overview]
Message-ID: <20070924100558.GA3943@pulp.rsise.anu.edu.au> (raw)

Hi all,
the following piece of code works as expected, but if I specify module
B1 as module rec B1 : sig ... end I get "Unbound type constructor s"

module type A1 = sig
    type t
end

module B1 : sig
    type s = int
    include A1 with type t = s
end = struct
    type s = int
    type t = int
end

The problem is even more evident here:

module type A = sig
    type t
end 

module rec B : sig
    type s = C.t
    include A with type t = s
end = struct
    type s = { c : int }
    type t = { c : int }
end
and C : sig
    type t = { c : int }
end = struct
    type t = { c : int }
end

This was a bug in Ocaml 3.07. Is this supposed to work in Ocaml 3.10 ?
I was unable to find a reference in the bug tracking system.
