optimum solution they are at least implementations of the functionality. I would gladly accept superior contributions ;-). I am also happy to spend more time improving them myself. I have to apologise for slow response times, my full-time job simply doesn't allow me enough time to contribute to this discussion as much as I probably ought to. You have made some very valid technical points, let's focus on these please.
My last post was not intended to put pressure on anyone to change anything, and I am very grateful for having boost. But Dave evidently thinks I am wasting everyone's time, and I beg to differ. If you agree that the general direction, self-contained iterators that use funky ranges to represent themselves efficiently, is right, I would bit by bit change my implementations of adaptor ranges and share them with you. I have not yet contributed to Boost, so probably my code is non-conformant all over the place, but it is a start.
