michael@0:    ECMA Section:       15.4.1 Array( item0, item1,... )
michael@0: 
michael@0:    Description:        When Array is called as a function rather than as a
michael@0:    constructor, it creates and initializes a new array
michael@0:    object.  Thus, the function call Array(...) is
michael@0:    equivalent to the object creation new Array(...) with
michael@0:    the same arguments.
michael@0: 
michael@0:    An array is created and returned as if by the expression
michael@0:    new Array( item0, item1, ... ).
