Yep, here's another dirty trick ;-): #include #define SPECIAL (whatever) #define IS_SPECIAL BOOST_PP_IS_UNARY IS_SPECIAL(a) // 0 IS_SPECIAL(b) // 0 IS_SPECIAL(SPECIAL) // 1 It isn't entirely portable to older preprocessors (that's why this code lives in preprocessor/detail) but should work with latest versions of the widely-used compilers.
