4756	Support for C++0x type_index in hash	ru.elric@…	Daniel James	"Boost hash currently does not support C++0x std::type_index. 

Boost has a #define for availability of <typeindex> header - BOOST_NO_0X_HDR_TYPEINDEX. Therefore, adding support for std::type_index should be pretty straightforward.

Something along the lines could do:
{{{
#ifndef BOOST_NO_0X_HDR_TYPEINDEX
#include <typeindex>

namespace boost {
  std::size_t hash_value(const std::type_index &v) {
    return v.hash_code();
  }
}
#endif
}}}
