1. std containers being ranges as defined in boost.range 2. a new concepts that refine the concepts of boost.range by adding iteration capabilities.
I believe (2) is exactly what John is doing.
-Thorsten
It's a mistake to think of John's range as being a refinement of the boost.range concept. If I have a non-const range and I pass it off to an algorithm that traverses it, will the range be modified or not?
Note: the range will *not* change (in case you pass it to a rng:: algorithm).
