i expected the following code to raise an error because the compiler doesnt know wich func to use, the template or non-template one
#include <string>
#include <iostream>
#include <cstdlib>
template<typename T>
T func(T arg) { return arg; }
std::string func(std::string arg) { return "surprise!"; }
int main(int argc, char **argv) {
    std::cout << func(std::string("no surprise please!") );
    return 0;
however the code always calls the non-template function. 
1.Why is that?
2.If that kind of behaviour is part of the standard (calling non-template functions rather than fitting templates), whats the point of the special syntax for template specialization?
std::string func<std::string>(std::string arg) { return "surprise!"; }
