Hello Hans,
in my experience .def(self+other) often didn't quite do what I expected.
You could try something like that:
int int__add__A_B(const A &lhs, const B &rhs){
return operator+(A,B);
}
.def("__add__", &int__add__A_B)
i.e. first define a non-overloaded function int_add__A_B and then bind it to
__add__ (which is the Python operator+ function).
regards,
Sebastian
