Yes. Changing iterator_traits (specifically, the collection of types associated with an iterator) is where I'm leaning, if you really want an unsigned iterator_range::size().
If you've got another / better solution for the signed/unsigned mismatches that result from a signed size() I'd be happy to hear it from you.
What would the problem be of just using std::size_t?
Well, likewise, what would be the problem of always using std::ptrdiff_t for difference_type? And, aside from whether std::size_t would be wide enough,
How is difference_type relevant?
I don't think there are any requirements that std::size_t be constructable from difference_type.
