And, ultimately, if there's ultimately just one call to begin/end on the final adapted range (the common case?), both the present implementation of the Boost.Range adaptors and a lazy implementation would go through the same sequence of iterator constructions, right?

The lazy case is actually able to perform some "optimizations" like eliminating double-reverses. It's not at all clear that these tricks would improve performance in reality, though. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
