Using default in a switch statement when switching over an enum

Question

What is your procedure when switching over an enum where every enumeration is covered by a case? Ideally you\'d like the code to be future proof, how do you do that?

I am not a C++ guy. But, in C#, I whould have written it like

enum Enum
{
    Enum_One,
    Enum_Two
};


Special make_special( Enum e )
{

    if(Enums.IsDefined(typeof(Enum),(int)e))
    {
       switch( e )
       {
          case Enum_One:
              return Special( /*stuff one*/ );
          case Enum_Two:
              return Special( /*stuff two*/ );
       }
    }
    // your own exception can come here.
    throw new ArgumentOutOfRangeException("Emum Value out of range");

}
