As far as I know, this isn't documented and it seems like something worth calling out

Relevant: rust-lang/rust#51129

impl !Trait isn't stable. It appears in the docs and is mentioned in the section on auto traits, but otherwise shouldn't be added until and unless it proceeds to stabilization.

I know it's not stable to implement, but someone who is using stable Rust still needs to have an understanding of how it works, right?
