It generates the right code, that works just fine

I am not sure I understand you. What do you mean under in/out arguments.

I guess you are doing wrong something else. Py++ contains
call_policies_tester.py. You can see that I use return_arg policy and
it works just fine. If you want to return int you should pass 2 to
call policy as argument.
If you can create small and complete example I will be glad to help you.
