Aren't standard containers supposed to satisfy the Range concepts? When the container is destroyed, its iterators are invalidated, right?
Yes, containers satisfy Range concepts, but this question is more related to the opposite relationship. There is no need for a range destruction to invalidate the iterators, and this leads to simpler code for example when creating a temporary range to pass to a range algorithm.
So? No algorithm could possibly _rely_ on the fact that the iterators will be invalidated, so what does it matter? You can do whatever's most efficient. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
