How do you get a pointer to an empty sequence? Unless you are talking of
iterators in the sense of the STL...

yes, that is exactly what I'm referring to. An iterator can be
implemented as a pointer, with the end() iterator being "one past the
end". In the case of an empty sequence, you may well use a NULL pointer
to store the result of both begin() and end().

But the wording of 5.7/3 seems to imply that the end() iterator cannot be a
NULL pointer.
