How can I output the value of an enum class in C++11

Question

How can I output the value of an enum class in C++11? In C++03 it\'s like this:

#include 

using namespace std;

enum A {
  a =

Following worked for me in C++11:

template 
constexpr typename std::enable_if::value,
                                  typename std::underlying_type::type>::type
to_integral(Enum const& value) {
    return static_cast::type>(value);
}
