Ask @asottile for help

hi @asottile, I love your youtube/twitch videos on typing. I have run into a small typing dilemma that I outlined in this repo, I was wondering if you might want to take a stab at it / have some time to give me some help (see the README and main.py for fully stdlib/self-contained example).

Could serve as a good short video, which demonstrates the new python 3.13 TypeVar syntax for default types.
