Yes. Guessing the languages is IMO too fragile. Plus, C code *does*
reference vtables in libio, and could easily do so elsewhere as well.
That sort of thing is popular with COM style programming.
Open issues:
(1) How to indicate (without a linker warning) that the object
implements some sort of "reflector" that can invoke any
class method. Mozilla implements such a thing.
(2) How to indicate "local classes" that will never be seen
outside of a module. This would make it meaningful to do
vtable gc on a shared library.
