An interesting omission, I'm a little surprised at that. But if your
switch to Py3 is a serious (or even half-serious) possibility, I
recommend tossing a quick comment against that line of code. Check to
see if you actually need it, and if you still do, see if there's a
change there. The module has been renamed (from __builtin__ to
builtins, although the global reference to it is still __builtins__),
so you may need to adjust something there, too. But mainly, see if you
can drop that line of code in Py3.

This part does make sense, though. Normally, module-level code runs
with the same locals and globals:

>>> locals() is globals()
True

And that doesn't change in Py3, so I would expect that your C++ code
also won't change.
