Template specialization for an empty parameter pack

Question

I have a variadic template function which calls itself to determine the largest number in a list (constituted by the templatized arguments). I am trying to make a specializa

Answer 1

Personally, I'd prefer using static class members over functions for this sort of thing:

template  struct max;
template  struct max {
  static const int value = max::value>::value;
};    
template  struct max {
  static const int value = N > M ? N : M;
};

int main()
{
  return max<1,2,3>::value;
}

Update: Using ildjarn's suggestion, here's the less verbose version:

#include 
template  struct max;
template  struct max
  : std::integral_constant::value>::value> { };
template  struct max
  : std::integral_constant M ? N : M)> { };
