Hi Neal. I suppose you read my posts on boost.python mailing list.
If not you suggest you to read them.

Any way, I implemented the missing functionality. In your case

struct A {};

struct B {
 A& a;
};

py++ will create next code:


#include "boost/python.hpp"

#include "1.h"

namespace bp =3D boost::python;

struct B_wrapper : B, bp::wrapper< B > {

    static ::A & get_a( B& inst ) {
        return inst.a;
    }

    static void set_a( B& inst, ::A & new_value ){
        inst.a =3D new_value;
    }

};

BOOST_PYTHON_MODULE(pyplusplus){
    if( true ){
        typedef bp::class_< B_wrapper, boost::noncopyable > B_exposer_t;
        B_exposer_t B_exposer =3D B_exposer_t( "B", bp::no_init );
        bp::scope B_scope( B_exposer );
        B_exposer.def( "get_a"
                , (::A & (*)( ::B ))(&B_wrapper::get_a)
                , bp::return_value_policy<
bp::copy_non_const_reference, bp::default_call_policies >() );
        B_exposer.def( "set_a"
                , (void (*)( ::B,::A & ))(&B_wrapper::set_a)
                , bp::default_call_policies() );
    }

    bp::class_< A >( "A" );
}

You can change call policies for every function using getter_call_policies
and setter_call_policies of variable_t class.

It would be nice if you can try new functionality and report problems and/o=
r
suggestions. I did some testing, but not a full one.

Thanks
