+==========================================
+
+Warns when a local non trivial variable is unused within a function.
+The following types of variables are excluded from this check:
+
+* trivial and trivially copyable
+* references and pointers
+* exception variables in catch clauses
+* static or thread local
+* structured bindings
+
+This check can be configured to warn on all non-trivial variables by setting `ExcludeTypes` to `.*`.
