Hi!

While rebuilding the python related packages against the Python 3.15rc2
version I ran into this FTBFS [1].

To solve the problem I had to do two changes:
- Apply upstream fix df5b4fd300cdbdd4cda920a27fdc5257f3cfea26 "Fix
   compilation and tests with C++20 (#64)"
- The tests depend on sagemath, which doesn't work with the current
   Python versions, so I replaced that test with a simpler one.

I've applied these fixes in the sandbox [2] to verify that it builds
successfully, these should be applied in Debian to get brial back to a
healthy state.

Happy hacking,
