Implement suggestion for never type fallback lints r? ```@WaffleLapkin``` Just opening this up for vibes; it's not done yet. I'd still like to make this suggestable in a few more cases before merge: - [x] Try to annotate `_` -> `()` - [x] Try to annotate local variables if they're un-annotated: `let x = ...` -> `let x: () = ...` - [x] Try to annotate the self type of a `Trait::method()` -> `<() as Trait>::method()`. The only other case we may want to suggest is a missing turbofish, like `f()` -> `f::<()>()`. That may be possible, but seems overly annoying. This partly addresses https://github.com/rust-lang/rust/issues/132358; the other half of fixing that would be to make the error message a bit better, perhaps just special casing the `?` operator 🤔 I don't think I'll do that part.
