I disagree with this interpretation. For me, Table 72 states the requirements
that InputIterators have to satisfy. It doesn't list defining iterator_traits,
and I don't think 24.3.1 wants to come back and add this requirement.

This also appears to be the interpretation that libstdc++ takes in most
places.

What do others think about this?
