There is already boost::move_iterator in Boost.Move Please make sure that move iterators and ranges are Input and not anything else, regardless of what the standard says. The standard is dangerously wrong in this regard.
Thanks for the advice. It's because the user might by mistake go through some elements more than once which would result in some number of moves from the same element or do you have something more surprising in mind? Unfortunately the boost::move_iterator follows the standard here. And since it's already in Boost it probably shouldn't be changed to ensure backward compatibility. We could of course implement different one and use it in Boost.Range but I'm not sure if this is a good idea. Should we have two different move_iterators in Boost? Regards, Adam
