using std::min; min BOOST_PREVENT_MACRO_SUBSTITUTION ( a, b );
I have 2 questions: 1) Is this the best name for the macro? Perhaps people would prefer something shorter. I'm open to suggestions.
You can always use BOOST_PP_EMPTY. using std::min; min BOOST_PP_EMPTY()(a, b); I'll point out again that you have to be careful with either of the above methods if they are ever used as an argument to a macro. This causes more than one scan of the pp-tokens, which will allow min and max to expand as macros if they are macros: #define EXPAND(x) x EXPAND( min BOOST_PP_EMPTY()(a, b); ) On a reasonably conformant preprocessor, the above or similar will still expand min if it is a macro.
