I like that.  I think you and Patrick have the same intent, and now 
we're just struggling to express it clearly.

Yes, I think something like that language would make sense.

There are a couple of cases where stuff must be calculated, even though 
you might THINK they don't need to be calculated. E.G.:
Isn't always 0; the referenced cell might contain an error.
But that doesn't invalidate this approach.
