#define STRINGIFY(S) #S
#define DEFER_STRINGIFY(S) STRINGIFY(S)
#define PRAGMA_MESSAGE(MSG) _Pragma(STRINGIFY(message(MSG)))
#define FORMATTED_MESSAGE(MSG) "[TODO-" DEFER_STRINGIFY(__COUNTER__) "] " MSG " \n" \
DEFER_STRINGIFY(__FILE__) " line " DEFER_STRINGIFY(__LINE__)
#define KEYWORDIFY try {} @catch (...) {}
// 最终使用下面的宏
#define TODO(MSG) KEYWORDIFY PRAGMA_MESSAGE(FORMATTED_MESSAGE(MSG))
