]> 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. -- Stefano Zacchiroli -- Master in Computer Science @ Uni.
