This has nothing to do with permutation iterator at all. An iterator is not expected to have a const_iterator member. It looks for all the world like user error: F expects a model of Range, and you're just passing a model of Iterator.
Yes, thanks, I meant to pass a range. I should stop posting early Monday morning.
