Hmm, this is yet another approach, one I hadn't accounted for
(or thought of). You're right, you could completely hide this via
functions, which might not be displayed on some systems (due to their semantics).
One challenge is that you may have ranges of numbers, and all functions
that take ranges must specify the difference too. The traditional way has
been to append an "A" at the end of some function names; that won't work for all.
I would add that you probably want a "VALUE-like function, but don't show it
to me", since people will want a VALUE() that shows, too.
This might really be a good solution. Can you post an expansion on this idea,
asap?
