Subject:	[Caml-list] Using %identity for casting types

Hi,

  I'm doing some experiments in interfacing OCaml with C++ and
  it is sometimes necessary to cast one type to another.
  I've seen in lablgtk something like:
    external unsafe_cast : 'a obj -> 'b obj = "%identity"

  It is meant to be used by the end user?

  Thanks.
