Comment (by Shunsuke Sogame <pstade.mb_at_[hidden]>):

 Replying to [comment:1 nesotto]:
 > AFAICT, you can't even use boost::ptr_vector<int const>, because the
 whole library has not been designed/tested with this in mind.

 Sorry again.

 See this:
 {{{
 #include <boost/ptr_container/ptr_vector.hpp>
 #include <boost/range/const_iterator.hpp>
 #include <boost/mpl/assert.hpp>

 int main()
 {
     typedef boost::range_const_iterator< boost::ptr_vector<int> >::type
 citer_t;
     BOOST_MPL_ASSERT((boost::is_same<citer_t::value_type, int const>)); //
 pass
     BOOST_MPL_ASSERT((boost::is_same<citer_t::value_type, int>)); //
 failed
 }
 }}}

 This seems a bug.
