I was confused by "top-level or-patterns are not allowed in let bindings" error, because it sounded like or-patterns were completely unsupported.

This error has an auto-fix suggestion that shows otherwise, but the auto-fix isn't always visible in IDEs.

I've changed the wording to be consistent with "Fn bounds require arguments in parentheses", and it doesn't sound like a dead-end any more.

Improved error message for top-level or-patterns

I was confused by "top-level or-patterns are not allowed in `let` bindings" error, because it sounded like or-patterns were completely unsupported.

This error has an auto-fix suggestion that shows otherwise, but the auto-fix isn't always visible in IDEs.

I've changed the wording to be consistent with "`Fn` bounds require arguments in parentheses", and it doesn't sound like a dead-end any more.
