+### What it does
+Checks for wildcard enum matches using `_`.
+
+### Why is this bad?
+New enum variants added by library updates can be missed.
+
+### Known problems
+Suggested replacements may be incorrect if guards exhaustively cover some
+variants, and also may not use correct path to enum if it's not present in the current scope.
+
+### Example
+```
+match x {
+    Foo::A(_) => {},
+    _ => {},
+}
+```
+
+Use instead:
+```
+match x {
+    Foo::A(_) => {},
+    Foo::B(_) => {},
+}
+```
