I'm doing some preprocessor meta-programming and I need a way to convert f(a b) to g(a,b) in C++ preprocessor. Since a and b are two tokens in C++, it seems possible to find a way to separate them. However, after hours of work there is still no solution to this problem.
Any third-party library including boost::preprocessor is welcomed given that these libraries work in preprocessing process.
Moreover, is there any way to separate arbitrary tokens? e.g const T& should be converted to const, T, &
