+ The Function 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 Function behaviour must include a super call
+ to the Function constructor to create and initialize a subclass instances with
+ the internal slots necessary for built-in function behaviour.
