Hi,

The series looks nice and LGFM for me

One pick on this:
--8<---------------cut here---------------start------------->8---
+     (list #:test-flags #~(list "-k" "not test_main")
--8<---------------cut here---------------end--------------->8---
May you provide a comment why it's deselected?

By the way PiPI https://pypi.org/project/clingexplaid/#files contains
tests and set version, so you may reduce package complexity if you pull
from there, no need to adjust version in pyproject.toml.

Thanks,
