Re: [boost] bounded_iterator

Maybe add these:

template<typename range_type>
inline bounded_iterator<typename boost::range_iterator<range_type>::type>
make_bounded_iterator (range_type & r) {
  return bounded_iterator<typename boost::range_iterator<range_type>::type> (r);
}

template<typename range_type>
inline bounded_iterator<typename boost::range_iterator<range_type>::type>
make_bounded_iterator (range_type const& r) {
  return bounded_iterator<typename boost::range_iterator<range_type>::type> (r);
}

Now you can do:

  template<typename out_t, typename in_t>
  inline out_t Map (in_t const& in) const {
    out_t out (boost::size (in));
    typename boost::range_iterator<out_t>::type o = boost::begin (out);
    typename bounded_iterator_type<in_t>::type i = make_bounded_iterator<in_t> (in);

    for (; i; ++i, ++o)
      *o = Map1 (*i);

    return out;
  }
