What makes it more difficult than marshalling parameters?

Another solution to allow an object state to be exported would be to add
a `get_state ()' method added to the interface definition that would
return a CORBA struct representing the object state.  However, this
requires, on the server side, to implement it by hand while value types
could automate this.
