I don't think that'll be a good solution to this problem, not efficient
enough.
Using this approach would introduce redundant overhead of checking equality
of iterators.

No, as I know, there's no such thing in Boost. If you really want one,
boost::iterator_facade can help you.

For myself, I'd prefer making some generic algorithms like
for_each_in_depth<n>(range, func) instead.
