#include <boost/utility/identity_type.hpp>
#include <utility>

int main()
{
   BOOST_IDENTITY_TYPE(( std::pair<int,int> const )) x;
   // This compiles, so the const qualification in the
   // above macro parameter is ignored.
   x = std::make_pair(0,1);

   return 0;
}

The omission of const qualification in BOOST_IDENTITY_TYPE types is  
undocumented. This omission maybe deduced from the documented  
implementation, but, as noted, that is not part of the library api and is  
subject to change. I therefore propose that this behaviour be documented  
as part of the library's public api.
