Would those work with a foreach construct? Perhaps I forgot to mention that was
what I'm trying to work out here.

In example 3 I was wondering if we could define a method reverse(). We could use
sfinae to wrap that around rbegin/rend if people like that style?

Sorry, I was too terse... ;)

If MF is a reverse_iterator, it'd just work, no? But to get the
reverse iterator, I think reverse() would be the best general pattern,
since you can adapt it to each container needs.
