yes, difference might be that i meant it in the sense that \use\match
wouldn't execute \match, it would only install it at its destined
position within the hash (if that's possible at all), so that you from
then on can call it by a simple \match. (which gets tricky if in the
meantime a macro with the same name has been defined)
