Boost.Move is really similar to what you are proposing, but it also handles the case that the compiler actually supports rvalue-references. So BOOST_RV_REF is a macro defined as: #ifdef BOOST_HAS_RVALUE_REFS #define BOOST_RV_REF(TYPE) TYPE && #else #define BOOST_RV_REF(TYPE) boost::rv< TYPE >& #endif It is true that macros always look ugly, but this is exactly the situation where you have to use a macro to abstract away unavoidable language differences.
