Why not keep all of the Boost versions in namespace boost, but create a
boost::tr1 namespace that has the appropriate using declarations for
the std versions (when a TR1 implementation is available) or the Boost
versions (when a TR1 implementation is not available). If we're feeling
really brave we could eventually call the boost:: versions deprecated
