A language binding could for each GSomeObject automatically generate a
subclass GSomeObjectWrapped where all the virtual functions were
mapped to virtual functions in the language.  Then it would be
possible to subclass and override virtual functions with classes
defined in the language.

Ok, this is probably stretching the spec too far.

I think I saw such objects in BSE a long time ago.  But perhaps this
should simply be considered evil with respect to wrappable API.
