  24     ECMA Section:       15.4.1 The Array Constructor Called as a Function
  25
  26     Description:        When Array is called as a function rather than as a
  27                         constructor, it creates and initializes a new array
  28                         object.  Thus, the function call Array(...) is
  29                         equivalent to the object creationi new Array(...) with
  30                         the same arguments.
