TIL this thing exists, haven't tried yet but I am seriously considering it. Orphan rule is something that made me switch to Zig, I am now back and so is orphan rule to get in my way :-/

BTW: It was already discussed many times in rustc repo, and it's clear that there's no serious downside for apps, but no action was taken. I am sharing this in a hope to make some peer pressure...
