The noxfile is much zippier now. I had to make some similar changes to what Dennis has. I'd assumed the problem then was some kind of interaction with Poetry, but apparently pip install . is just Like That? I've also got a helper script that gets the mutation testing done in like ten minutes. Which is awesome. Now I can run the tests and, like, read an article or something, instead of, run the tests, eat a full meal, watch some videos, still not done, what is happening...
I'm working on shoring up the features in Structured Data, and that means removing some of them, because I do not understand them well enough to fully implement them.
This was a little unsettling, because removing the features didn't alter the tests or coverage any.
I don't have anything else in mind and I'm really tired, so, good night.
