should one be able to add, subtract, and compare mutable random access iterators with random access const_iterators provided they point to the same container?
There is no requirement that it be possible, and many early STL implementations failed to make it possible. It's generally regarded as a poor QOI that doesn't allow it. That capability is one of the things that iterator_facade and iterator_adaptor make easy. -- Dave Abrahams Boost Consulting www.boost-consulting.com
