I really dislike the magical "<" business.  Maybe you could use NULL
instead of having to reserve a class of real strings as placeholders.
(That would require finding another way to denote the end of the list,
but a separate count argument seems like a possible answer.)
Or perhaps use empty strings as placeholders?
