[boost] problem with permuation_iterator (constness)

This simple test illustrates the problem: #include <boost/iterator/permutation_iterator.hpp> #include <vector> #include <boost/range.hpp> template<typename in_t> void F (in_t const& in) { typename boost::range_const_iterator<in_t>::type inp = boost::begin (in); } int main () { std::vector<int> x, y; F (boost::make_permutation_iterator (boost::begin (x), boost::begin (y))); } /usr/local/src/boost.hg/boost/range/const_iterator.hpp:37: error: no type named const_iterator in class boost::permutation_iterator<__gnu_cxx::__normal_iterator<int*, std::vector<int, std::allocator<int> > >, __gnu_cxx::__normal_iterator<int*, std::vector<int, std::allocator<int> > >
