We should probably also add 3.10 to the Python versions tested in test.yml. Maybe we should also bump the Python version 3.6 in test.yml since 3.6 is near end-of-life.

But these should probably go into a separate PR.

Not sure whether the failing tests can have anything to do with what I've been doing here.

Yes, the tests are failing not because of the PR but because I added a test a week ago that checks the version of byexample in the documentation, but it was designed to work in the developer's environment, not in CI/github.

Also, the tests for Golang are failing. I tracked the issue to a problem in upstream (in the interpreter of go).

I will review this PR today late but I think it perfect.

Thanks for the contribution!

I ran the tests and everything worked perfect. Merging. I will cut a new release probably at the end of the week.

Thanks a lot!
