Broken on both python 3.10 and 3.9 (caught that one in CI), seemingly by #27 .

I presume like there should be an optional dependency typing-extensions for py < 3.10, and for 3.10 and above ParamSpec should be imported from typing instead - from my understanding, said typehint got merged from extensions into stdlib in 3.10 release.

FYI: if you look at the GHA run corresponding to #27 https://github.com/alice-biometrics/meiga/runs/7740328032?check_suite_focus=true , typing-extensions is actually installed there as a dependency of lume:

Run pip install lume
Collecting lume
  Using cached lume-0.9.2-py3-none-any.whl (33 kB)
...
Collecting typing-extensions>=3.7.4.3

This is how it leaked to production.

You are absolutely right, the lume dev dependency was masking this incorrect behaivor.

In the linked PR I've been able to reproduce your reported error:

https://github.com/alice-biometrics/meiga/actions/runs/2921291258

Then I solved the problem based in what you proposed.

In addition, I have also added to the test array the python 3.11-dev version: 😄

Thanks again for this bug report! 🥇
