>     Given 24.5.1.1 p1 and p2, it is pretty clear to me that the two iterators are both
non-end-of-stream type, and they are both created on different streams. The streams are different,
so the iterators should not compare equal. I guess one could claim that 24.5.1.2 p6 conflicts
with 24.5 p3 because 'end-of-stream' isn't clearly defined, but in this particular case that
doesn't matter.
