>It almost seems as if a type which matches no values should have the unusual quantifier of zero.

I handled it that way at one time but it caused too many problems. I now type
error() as item(), which works for optimistic typing - it means that error()
will never cause a static type error, except in the pathological case where the
required type is empty-sequence(), because item() overlaps every other type.
(Perhaps I should have chosen item()? which would work for empty-sequence() as
well...)
