Very interesting FOSDEM talk which I see as part of the debate about "Open Source as just licenses"/"Post Open Source". This shows very well how the OSD is very narrow and that their should be a better alignment between what is labelled FOSS and the actual customs. This is something which licenses alone can't capture.

Looking forward to Python 3.10 in October which will finally get pattern matching!

Interesting use of reference_wrapper... I wonder why it didn't occur to me earlier as a good use to deal with ownership like that.
