Sylvia, if you have any control over the name of your zip files, please use something shorter.  ;)

The files inside are a 'main.py' and a 'module.py' -- notice there is no '__main__.py'.  So it can't be executed as 'python3 -m blahblah'.

I tried renaming 'main.py' to '__main__.py' but then I get either

  ImportError: cannot import name 'Module'

or

  ImportError: No module named 'module'

I'm happy to check for strange Enum interactions, but I need a working test case first.
