@smunix Thanks for updating spatial-math and not-gloss. I look forward to spatial-math-0.5.0.2 being on hackage. Is there a workaround in the meantime?

I build with with Nix, which allows me to pull directly from github:smunix/not-gloss?ref=fix.nix (see my changes to your original repository to get it to compile with ghc-9.2). It's one way to go around it.

An easier workaround would be to add a cabal.project file to your project, then use it to point to my remote git repository (see cabal doc here). IIRC, your github:walck/learn-physics already uses cabal, so we should be able to add cabal.project to it. Let me know if you'd welcome PR to it, I can help with that

BTW, thank you for your great contribution!!!
