Anonymous Namespace Ambiguity

Question

Consider the following snippet:

void Foo() // 1
{
}

namespace
{
  void Foo() // 2
  {
  }
}

int main()
{
  Foo(); // Ambiguous.
  ::Foo(); // Calls the Foo         


        

Answer 1

While Georg gives standard-complient, correct, right, and respectable answer, I'd like to offer my hacky one - use another namespace within the anonymous namespace:

#include 

using namespace std;

namespace
{
namespace inner
{
    int cout = 42;
}
}

int main()
{
    cout << inner::cout << endl;
    return 0;
}
