Yes, but the compiler knows which interface it wants,
so there's no ambiguity. Dynamic binding only occurs
at the interface level. Once you have the interface,
getting the method is just a table lookup.

Each interface requires a single set of methods, whether
through declaration or inheritance, so there's no need
for a special case.
