| 22.1.1 The Array Constructor |
| |
| The Array 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 exotic Array behaviour must include a super call to the |
| Array constructor to initialize subclass instances that are exotic Array |
| objects. |
