IIRC this was due to multiple unheritance. You could inherit methods
with the same name and parameter list from two different base classes.
Disallowing that at declaration time would mean disallowing
inheritance (even indirectly) from these two base classes, even though
the derived class didn't use the ambiguous methods.
