These are "must be" installs, which is not true for zero. It is only needed for the test and not needed for package distribution. Please remove this.

verify_function_typing name is not clear, it verifies and returns something, doing 2 things but the name suggests it only verifies

I don't think "inspect" is a good solution. Most of the tests are failing, it cannot even compare types, as an example list is supported type but it fails to recognize it

@trollfot thank you for the PR! 🙌 Unfortunately, the tests are failing and I think "inspect" is not a good solution for thorough type checking. I have tried it before but forgot why didn't use it 😞 |
