C++ type information at run time

std::type_info::name and typeid(T).name() will give incorrect results, as required by the standard

use Boost.TypeIndex

#include <boost/type_index.hpp>

boost::type_index::type_id_with_cvr<T>().pretty_name();
boost::type_index::type_id_with_cvr<decltype(t)>().pretty_name();
