#9562: boost::detail::operator_brackets_proxy::result_type::operator= return type
is wrong

 From boost/iterator/detail/operator_brackets_dispatch.hpp:

 {{{
 template <class Iterator, class Reference>
 struct operator_brackets_proxy
 {
     class result_type
     {
         Iterator const m_i;
         explicit result_type(Iterator const & i) : m_i(i) { }
         friend struct operator_brackets_proxy;
         void operator=(result_type&);
     public:
         operator Reference() const { return *m_i; }
         operator_brackets_proxy const & operator=(
           typename Iterator::value_type const & x) const
         { *m_i = x; return *this; }
     };
     static result_type apply(Iterator const & i)
     { return result_type(i); }
 };
 }}}

 The return type of `result_type::operator=` should be `result_type const
 &`, not `operator_brackets_proxy const &`. This looks like a typo.
