+
+  A semicolon-separated list of names of types that
+  will be excluded from const-correctness checking.
+  Regular expressions are accepted, e.g. `[Rr]ef(erence)?$` matches every type
+  with suffix `Ref`, `ref`, `Reference` and `reference`.
+  If a name in the list contains the sequence `::`, it is matched against
+  the qualified type name (i.e. `namespace::Type`), otherwise it is matched
+  against only the type name (i.e. `Type`).
