[C++-sig] C++ derived from bp::dict

[Stefan Seefeld]

Hi Michael,

I strongly doubt that what you want is possible.

While class_<A> generates a Python type that wraps 'A', 
boost::python::dict itself is not built that way. Rather, it is a proxy 
to a Python dict object. Types defined via "class_<>" are added to a 
type registrar, which is inspected whenever a C++<->Python conversion is 
requested. I strongly doubt that the boost::python::object derivatives 
are themselves registered there.

Besides, Python has strong requirements concerning what types are 
allowed to derive from what base types (as far as the associated 
meta-classes are concerned), which I don't think are met by the above.
