I'm letting pip stuff just kind of stew in the back of my mind, so it feels less like I'm going in circles for a bit.
I did a few things that I'll want for the virtual tabletop stuff, like putting in a bug against another Python implementation, basically asking "Here is a thing that does not work like in CPython, is this desired/acceptable?" I also put together a tiny cursèd shim that should make trio compatible with Python 3.7+ implementations besides CPython and PyPy. It's extremely sketchy.
Anyway, I'm still looking for a balance between "I'm having trouble focusing on stuff" and "I just want to get this done". I'm not going to come up with answers to that, or anything else to talk about, in the next few minutes, so time to wrap up.
