  24     ECMA Section:       15.4 Array Objects
  25
  26     Description:        Whenever a property is added whose name is an array
  27                         index, the length property is changed, if necessary,
  28                         to be one more than the numeric value of that array
  29                         index; and whenever the length property is changed,
  30                         every property whose name is an array index whose value
  31                         is not smaller  than the new length is automatically
  32                         deleted.  This constraint applies only to the Array
  33                         object itself, and is unaffected by length or array
  34                         index properties that may be inherited from its
  35                         prototype.
