there'll be no way to distinguish the property by interface for
the same instance.
basically interfaces can just "request" for an instance to implement
a certain property, so there really is nothing to distinguish.
so something like IntIface requesting Int::name, and StringIface
requesting string::name can't possibly work for a class that
is meant to implement both interfaces.
