Hrm, that patch helped, but it doesn't fix everything. For instance, I
can't do this anymore:

  #include <utility>
  #include <vector>
  #include <boost/range/iterator_range.hpp>

  int main()
  {
    std::pair<int,int> p(1,1);
    std::vector<std::pair<int,int> > v(2,p);
    boost::iterator_range<std::vector<int>::iterator> r(v.begin(), v.end());
    r[0].first; // ERROR
  }

I get the following error:

  1>c:\boost\org\trunk\libs\proto\scratch\main.cpp(10) : error C2039:
'first' : is not a member of
'boost::detail::operator_brackets_proxy<Iterator>'

This is breaking Boost.Accumulators. Can you look into it?
