That looks similar enough. But I think the Bidirectional iterator tag in the
case of sorting is expressive enough and for std::merge, either forward
iterator tags or output iterator tags would express the desired characteristics
suitably. If someone can't create an iterator without those needed tags but
can create an iterator with the required characteristics I would be very
surprised.
