The annoyance I've run into is mixing types traits from both std and Boost
(Boost has more type traits, so I cannot eliminate the dependency on Boost
in this case).  When doing tag dispatching, they have different tags, as
boost::true_type is a type unrelated to std::true_type.

On possible improvement for C++11 would be to have boost::mpl::integral_c
(the top level base class of boost::true_type) publicly derive from
std::integral_constant, but I don't know what the ramifications of that
would be.
