    ECMA Section:       15.4.4 Properties of the Array Prototype Object
    Description:        The value of the internal [[Prototype]] property of
                        the Array prototype object is the Object prototype
                        object.

                        Note that the Array prototype object is itself an
                        array; it has a length property (whose initial value
                        is (0) and the special [[Put]] method.
