It seems to me that the "%identity" feature, as in
external unsafe_cast : 'a obj -> 'b obj = "%identity"
is undocumented. Am I wrong? If not is there any particular reason for
so? According to http://caml.inria.fr/archives/200208/msg00034.html is
not meant to be used by the end user, but if it's better than Obj.magic
and used by lablgtk I see no reason to not mention it in the
"Interfacing C with Objective Caml" chapter of the OCaml documentation.
Maybe with a huge disclaimer ...
Cheers.
