    ECMA Section:       15.4 Array Objects

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