info: |
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.
