     9    ECMA Section:       15.4.1 Array( item0, item1,... )
    11    Description:        When Array is called as a function rather than as a
    12    constructor, it creates and initializes a new array
    13    object.  Thus, the function call Array(...) is
    14    equivalent to the object creation new Array(...) with
    15    the same arguments.
    17    An array is created and returned as if by the expression
    18    new Array( item0, item1, ... ).
