virtual method tables and operator overloading are orthogonal problems. Sure in many languages operator overloading is done using virtual methods, but it doesn't have to be. Operator overloading can dispatch based on static types rather than dynamic types.
That said, I do wish that there was a standardized way to expose vtables across foreign language boundaries. Although, I understand that differences in how vtables work across different languages, or even different implementations of the same language (cough cough c++ cough cough) would make creating a useful standard difficult.
