I'm willing to go to Py3 but only if the solution to the problem is
simpler than getting it fixed in Py2. So some questions first:

- does this importlib stuff you showed there apply to C++ land (I need
to fully drive it from C++ not Python code)?
- is the C++ land of Py3 similar to Py2 or totally different?
