Three Dollar Quill

Okay, I've made a serious dent in the mypy coverage holes for Structured Data. Now the main thing left is that I still haven't worked out what I want to do for how the Descriptor classes return different proxies based on which class they're accessed from.

I ended up feeling kind of sick today, so I don't have the energy to figure out if there's anything else I want to talk about now.

Good night.
