    ECMA Section:       15.4.1 The Array Constructor Called as a Function

    Description:        When Array is called as a function rather than as a
                        constructor, it creates and initializes a new array
                        object.  Thus, the function call Array(...) is
                        equivalent to the object creationi new Array(...) with
                        the same arguments.
