No.

As you may know, _is_equivalent compares CORBA object references. It
does not compare CORBA objects, so two references that compare equal
definitely refer to the same object; two references that are not
equivalent may or may not refer to the same object.

That is not safe. If you call object_to_string() twice with the same
object reference, there is no guarantee that you will get the same
string. And, as with _is_equivalent, you can have two totally different
looking object references that refer to the same object.

The normal way to support object comparisons is to define your own
comparison operation in a base interface. Then you can ask an object if
it is the same as another one.
