Then let me suggest that there exist a
decoration for empty.
Or, at least, some combination of the
existing decorations that implies empty.
That way we do not NEED a representation
for empty within the interval part of a
1788 interval.
And we will have anything + empty = empty
fall out to be both fast & easy no matter
what we use for empty so long as the
decoration makes it so.
Since bare[1,1]/bare[0,0] or sqrt(bare[-2,-1]) must be empty,
this conflicts with the need of a fast mode for arithmetic
operations for bare intervals.
