+  21.2.3 The RegExp Constructor
+
+  ...
+
+  The RegExp constructor is designed to be subclassable. It may be used as the
+  value of an extends clause of a class definition. Subclass constructors that
+  intend to inherit the specified RegExp behaviour must include a super call to
+  the RegExp constructor to create and initialize subclass instances with the
+  necessary internal slots.
