#include <iostream>

namespace NS {

template<class T>
struct A {
    T t;
};


template<class T>
void f(T &t)
{
    std::cout << "function 1" << std::endl;
}       

template<class T>
void g1(T &t)
{
    // qualify with namespace
    NS::f(t);
}

template<class T>
void g2(T &t)
{
    // do not qualify with namespace
    f(t);
}

template<class T>
void f(A<T> &t)
{
    std::cout << "function 2" << std::endl;
}

}

int main()
{
    using namespace NS;
    A<int> a;

    g1(a);      // this should print: "function 2", bug?
    g2(a);      // this prints "function 2" correctly.
    return 0;
}
