Could you include a very specific header, eg called <for>, with just
whatever it is "for" needs, and require that header to be #included by
<iterator> and <vector> and the other containers?

Or some similar mechanism... obviously there needs to be a way for end
users to get the support for their own containers, and although I suppose
just #including <iterator> would do, a smaller header might be better for
the same reason that <vector> doesn't #include <iterator>.

I appreciate that having standard headers document what other headers they
include is a new thing. Would it be a problem in this case?
