How to resolve the recursive reference issue?

[softempire]

I have two C++ classes

class A
{
public：
    B* methodA();
}

class B
{
public:
    A* methodB();
)

When I define the Python wrapper with

py::class_<A>(m, "ClassA")
       .def("method_a", &A::methodA);
py::class_<B>(m, "ClassB")
       .def("method_b", &B::methodB);

The method_b for ClassB will return the underlying C++ type instead of the Python type. How can I resolve the problem?

Should I use the following method:

 py::class_<A> classA (m, "ClassA");
 py::class_<B> classB (m, "ClassB");
 classA.def("method_a", &A::methodA);
 classB.def("method_b", &B::methodB);
