Can we retain an example of what makes something "uninhabited" in this case, or a link to documentation that describes the notion of something being uninhabited?

I struggled a bit with what to say here and would welcome suggestions.

A quick grep indicates this is the first time we're using the word in the standard library documentation. But the reference: https://github.com/rust-lang/reference/blob/master/src/glossary.md?plain=1#L284-L289 and the dev guide: https://github.com/rust-lang/rustc-dev-guide/blob/master/src/appendix/glossary.md?plain=1#L93 both provide a definition.
If we need to put a definition in the standard library docs I'm not sure where it would go, but I'd be happy pasting either of these in. Or just directing people to the reference, though that sounds bit-rotty unless we have something that checks that a link to that specific glossary entry still works.

Since I don't think (un)inhabited types should be special-cased here, I have chosen an entirely different wording now.

Yeah, this looks correct. @bors r+ rollup |
