Impossible, I think, unless we change the iterator requirements to allow
proxied forward iterators.  (i.e. forward iterators where *it returns 
something other than T& or const T&.)

I'd be very interested in trying to figure out what we need to do to allow
proxied iterators.  They don't quite work, but there are a lot of places
where they'd be useful.  It might be impossible without language changes.
