I doubt there may be a sequence of length 0 at NULL. How would you allocate such a sequence?
Actually, every iterator (singular, initialized, pointing to viable memory or not) defines its own empty range.
No, I don't believe that's quite correct. There are lots of things one can do with iterators in a range that one cannot do with a minimally-singular iterator. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
