    ECMA Section:       15.4.4.2 Array.prototype.toString()
    Description:        The elements of this object are converted to strings
                        and these strings are then concatenated, separated by
                        comma characters.  The result is the same as if the
                        built-in join method were invoiked for this object
                        with no argument.
