Very much interested by the topic.

For reference I tried to summarize the status of inline type and value validation here: https://smarie.github.io/python-valid8/why_validation/

And I proposed a solution with a library here https://smarie.github.io/python-valid8 (with a somewhat smart handling of the ValueError / TypeError inheritance dilemma, for what's worth)
