[Message part 1 (text/plain, inline)]
Hello!

I stumbled across this bug after re-discovering that Python bytecode is
not reproducible (through "glib"). Just sharing some notes..

Nix recently made an effort to fix this. AFAICT the ".pyc" files are
still a problem, but at least they got the interpreters building
reproducibly:

https://github.com/NixOS/nixpkgs/pull/22585

It would be great to revive this longstanding bug!
