Actually, there's a few cases where it might be useful - e.g.
Target_Count : Byte_Array (-90 .. 90); -- number of objects detected in
a -90 degree .. +90 degree arc, to 1 degree resolution.
Other uses include values related to floors of a building that contains
sub-basements, lookup tables that are indexed by +/- temperature,...
Even if you don't like negative numbers, at least starting with zero permits
certain small but useful optimizations on some architectures.
