I don't think that will change -- super passes along all the original
arguments too (unless told otherwise with (arglist)).  It's a special
case: repeat the call to this method, but skip the current method in
the method search-chain.  It's rather as if the current method has
steamed the envelope open, peeked inside, and then resealed it.
