c++ - Aliasing a function definition - possible VS2013 bug? -


i alias function definition, shown in code below. there compiler error when first function parameter not primitive type. assuming compiler bug. thoughts? there workaround using pre-processor, not ideal. compile error is: error c2061: syntax error : identifier 'string'

#include <iostream> #include <string> #include <functional>  void print1(int i, std::string s) {     std::cout << s << << std::endl; }  void print2(std::string s, int i) {     std::cout << s << << std::endl; }  int main() {     using fundefn1 = void(int, std::string);   // ok     //using fundefn2 = void(std::string, int); // error c2061: syntax error : identifier 'string'      // workaround...     #define fundefn2 void(std::string, int)      std::function<fundefn1> p1 = print1;     std::function<fundefn2> p2 = print2;      p2("hello world!", 42);     p1(42, "hello world!");      return 0; }
