Closes #157

Thanks.

I think there's a few files however we still need to update.
See this PR for 3.11, https://github.com/rustedpy/result/pull/107/files, for reference

Thanks!

I've added [Unreleased] record to the changelog and fixed tox.ini, but I don’t understand how to correctly use the test_result.yaml file

[francium]

You should be able to run pytest and it should pick up the yaml test. But as long as the PR passes checks, I don't know if we need any changes to the yaml file.

Thanks, I'll review this and test this myself when I get the chance.

Oh, cool, I didn't even know there was a way to run tests like that

type-checking/test_result.yml::failure_lash PASSED
type-checking/test_result.yml::covariance PASSED
type-checking/test_result.yml::map_ok_err PASSED
type-checking/test_result.yml::map_result PASSED
type-checking/test_result.yml::map_result PASSED

These tests pass, so we have fixed everything that needed =)

Thanks for the help @vkurilin
