/**
   File Name:          15.4.1.1.js
   ECMA Section:       15.4.1 Array( item0, item1,... )

   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 creation new Array(...) with
   the same arguments.

   An array is created and returned as if by the expression
   new Array( item0, item1, ... ).
