Thanks a lot, whant an awesome contribution! Could you please take a look at those two minor nitpicks I found? Also the pipeline is failing, could you take a look at that? I don't understand why the similarities check does not ignore function annotations, feel free to add ignore comment. If you need help with anything, let me know. Nice work!

[afi-dev]

I think I've applied the changes correctly, but please let me know if you need any further changes.

[tomasvotava]

Please take a look at the last thing, also, the pipeline is still failing, I am more of a ruff fan lately, so ignore it for now, I'll deal with it.

[tomasvotava]

It looks perfect now, could you please try rebasing from the master? I switched to ruff, I hope it won't break anything, but the pipeline should now pass.

git checkout master
git pull
git checkout -
git rebase master

That should do it. There will probably be some conflicts, I can help you resolve them if you have any troubles.

[tomasvotava]

I felt bad for requesting so many changes, so I went ahead and created a PR into your PR afi-dev#2 😁 it's all rebased, you only have to accept all incoming to resolve the conflicts. If you'd like to resolve yourself, feel free to close the pull request.

[afi-dev]

no problem

For me it's fine, I hope it's the last fix and that I haven't forgotten anything, after checking, there's nothing missing.
