	Hmm, the CORBA C mapping spec is old and stale. I would hope to
see a better approach to this in the new spec.

	_impl_copy ? surely we can fix it by doing:

	*(const MyString *) = _args [n];

	instead ?

	This would loose us a lot of useful protection.

	This sucks too :-)

	This makes more sense - do you have time to look into it ? we just
need to get the skel's arg munging and the prototype code to agree on the
types I would imagine. The headers, and skel prototype look correct to me.

	Regards,
