Just yesterday I was thinking I would like to have something like this. I didn't know that this type of feature had a name, nor did I know what it would/could look like, but now that I see it in this PEP, it looks awesome to me. Yes, it does also look like something that could be greatly abused. But I think the way to temper that is to add guidelines for it (for linting) and to not bring this feature up for learners until they've reached a more advanced level (which I figure will likely happen, as it will be new for most experienced Python coders for a while)
