You're quite correct! Thanks for pointing that out. I can think of two
possibilities:

1. Just document that non-const base() is public
2. Make the Policies class a friend of the iterator, and document that
non-const base() is private, but available to policies.

Hmm, it seems you can't declare a template parameter to be a friend. I guess
it's #1. Jeremy, any thoughts?
