Value types are a fairly high-level feature, and to implement them,
you need a whole lot of infrastructure on both the server side
(where you have to know what exactly constitutes the state of an
object) and the client side (where you have to create an object
of the same type with a specific state). Given that IDL4 is a stub
code generator and was never intended to be a full-blown CORBA
implementation, I would rather not add this feature unless someone
finds a real problem that cannot be solved efficiently without it.
