Just pretend I didn't write this paragraph :-(. I was going to
describe the other case first, then changed my mind. The previous
paragraph describes Case #2.
The text before and after this paragraph looks clear to me. Does
anyone else agree? I didn't think I had done any hand waving on
globals and module attributes in the slides; so I expect that I'm not
a good judge of what is hand waving and what is high-level
description.
