Indeed. They are not really in the class, after all. Also since separate
library is supposed to be able to provide them, it does not have access
to the private members at all, since they are not exported.

That's what I'd prefer too. Plus it would naturally make the C name the
same as if the method was really in the class, which I think it should.
