So, it's really important that you actually read and run the code, and let me know in the comments that you did. 🤓

///

* If the PR can be simplified in a way, you can ask for that, but there's no need to be too picky, there might be a lot of subjective points of view (and I will have my own as well 🙈), so it's better if you can focus on the fundamental things.

### Tests { #tests }

* Help me check that the PR has **tests**.
