The O'Caml compiler will later not be able to resolve A.T if you use
the `-d' option:
ohl@wptx47:~misc$ ocamldefun -v
1.02
ohl@wptx47:~misc$ cat a.mli
module type T = sig val n : int end
module M : T
ohl@wptx47:~misc$ cat a.ml
module type T = A.T
module M : T = struct let n = 42 end
ohl@wptx47:~misc$ ocamldefun -d defun a.mli a.ml
ohl@wptx47:~misc$ cd defun/
ohl@wptx47:~defun$ ls
a.cmd a.ml
ohl@wptx47:~defun$ cat a.ml
module type T = A.T
module M = struct let n = 42 end
ohl@wptx47:~defun$ ocamlopt a.ml
File "a.ml", line 1, characters 16-19:
Unbound module type A.T
I could ignore appendix B of the manual and create a a.cmi:
ohl@wptx47:~defun$ cp ../a.mli .
ohl@wptx47:~defun$ ocamlc a.mli
ohl@wptx47:~defun$ ocamlopt a.ml
but I'm not supposed to do that, am I?
BTW: given the (currently) uncertain semantics, I have started to
remove the construct from my applications.
