michael@0: 
michael@0:    Description:        Whenever a property is added whose name is an array
michael@0:    index, the length property is changed, if necessary,
michael@0:    to be one more than the numeric value of that array
michael@0:    index; and whenever the length property is changed,
michael@0:    every property whose name is an array index whose value
michael@0:    is not smaller  than the new length is automatically
michael@0:    deleted.  This constraint applies only to the Array
michael@0:    object itself, and is unaffected by length or array
michael@0:    index properties that may be inherited from its
michael@0:    prototype.
