 ### What it does
-Checks for bindings that destructure a reference and borrow the inner
+Checks for bindings that needlessly destructure a reference and borrow the inner
 value with `&ref`.
 
 ### Why is this bad?
 This pattern has no effect in almost all cases.
 
-### Known problems
-In some cases, `&ref` is needed to avoid a lifetime mismatch error.
-Example:
-```
-fn foo(a: &Option<String>, b: &Option<String>) {
-    match (a, b) {
-        (None, &ref c) | (&ref c, None) => (),
-        (&Some(ref c), _) => (),
-    };
-}
-```
-
 ### Example
 ```
 let mut v = Vec::<String>::new();
 v.iter_mut().filter(|&ref a| a.is_empty());
+
+if let &[ref first, ref second] = v.as_slice() {}
 ```
 
 Use instead:
 ```
 let mut v = Vec::<String>::new();
 v.iter_mut().filter(|a| a.is_empty());
+
+if let [first, second] = v.as_slice() {}
 ```
