That sounds great to me!

I can't really fault your logic.
I just thought of something that makes some sense. If the wrapper
did something like:
_wrap_my_virtual_method (A &a)
{
PyA *py_A;
py_A = PyObject_New(PyA, &PyA_Type);
py_A->obj = &a;
// --- code to call into Python (without consuming a reference to
py_A) ---
py_A->obj = NULL;
Py_DECREF(py_A);
}
At the end of the virtual method call, if the called python code
decided to keep a reference to py_A, it will have a py_A with NULL C+
+ object and so any method call on it will crash.
And this would not need any options. It's always best to do the
smart thing when possible without asking too many questions ;-)
