Yeah, I know about limitations of __traits. And I don't understand why
virtual functions are special-cased. If it is a temporary hack then I
don't understand why it is in the specification.

That is very bad. I hoped for some clever workaround. Really don't
want to rely on a patched compiler. Probably, will have to wait
another couple of years.
