Doubtless I'm more easily impressed than Gennaro, but to me the general idea of doing only the arities you need to *is* quite clever Sketch: #ifndef BOOST_FUNCTION_MAX_ARGS_CURRENTLY_AVAILABLE_PLUS_1 #define BOOST_FUNCTION_MAX_ARGS_CURRENTLY_AVAILABLE_PLUS_1 0 #endif #if (BOOST_FUNCTION_MAX_ARGS > BOOST_FUNCTION_MAX_ARGS_CURRENTLY_AVAILABLE_PLUS_1) //do file iteration from //BOOST_FUNCTION_MAX_ARGS_CURRENTLY_AVAILABLE_PLUS_1 to BOOST_FUNCTION_MAX_ARGS #undef BOOST_FUNCTION_MAX_ARGS_CURRENTLY_AVAILABLE_PLUS_1 #define BOOST_FUNCTION_MAX_ARGS_CURRENTLY_AVAILABLE_PLUS_1 (1+BOOST_FUNCTION_MAX_ARGS) //ready for next include #endif I'm not sure how much gain you will see in practice as the inner headers will themselves already have include guards, but perhaps worth investigating nonetheless.
