I *think* this definition still fulfils the use case for quarks themselves, but I wonder if it would involve a little too much code shuffling to be worth implementing for expl3. (And it makes it more difficult to peek inside a quark, if that's ever necessary.) Before I forget about this idea, does anyone have any comments on the matter? Cheers, -- Will
