  24     ECMA Section:       15.4.4 Properties of the Array Prototype Object
  25     Description:        The value of the internal [[Prototype]] property of
  26                         the Array prototype object is the Object prototype
  27                         object.
  28
  29                         Note that the Array prototype object is itself an
  30                         array; it has a length property (whose initial value
  31                         is (0) and the special [[Put]] method.
