I'm sorry, I can't take seriously any piece of software which decided to prefix the previous version's name with "based". I'm aware this is a me problem.
Hah. I love the name. It implies that whatever the original “pyright” was doing wasn’t keepin’ it real. This new version, it’s “based” so it must be somehow more “real” and “grounded” and “legit”.
All I know is it is much more strict about stuff than pylance was.
