So, I'm tinkering a bit with #Django, and I wanted to run different Django versions on the /same/ virtual machine. Here `#virtualenv` helps only insomuch that it can seperate dev envs, but it all still shares the `~/.local/lib/python3.10/site-packages` folder.
(I can't imagine this problem hasn't been solved, but couldn't find anything online.)
I've resorted to overriding HOME: basically I wrote a `virtualenvenv` script that I source, and then I have the separation I want/need.
