Expand let-else allow tests The #[allow(...)] directive was tested for the body and the pattern, but non-presence of it wasn't tested. Furthermore, it wasn't tested for the expression. We add expression tests as well as ones checking the non-presence of the directive. 2022-02-21 03:38:39 +00:00			`let Some(chaenomeles) = value.clone() else { return }; // OK`
