That looks correct.

The 3.4 version is also precompiled, but __file__ gives the filename
of the actual module (not the .pyc implementation detail).  You can
find precompiled token.py for 3.4 at
/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/__pycache__/token.cpython-34.pyc

Not so, the traceback you posted shows pretty clearly that the problem
is in the tokenize module, where the token module it has imported does
not have an __all__ attribute.

This should have failed with the same traceback as your test2.py.

Try your test again.  If it fails again, run my test again at the same prompt.
