Using classes defined later in the same file?

I'm working on adding stances to Player, and I want to store the stance enum in the Player class. But if I do this:
struct PlayerData {
   F32 maxForwardSpeeds[Player::NumStances];
};

class Player {
   enum Stance {
      NumStances
   };
};
I get a compiler error 'use of undefined type Player'. Can I solve this? Or do I need to use a static enum?

    A forward declaration of the Player class should help.

    Just put the single line

    class Player;

    above the struct.

    Still get the same error, unfortunately. That seems like it should have worked... Do I need to clean and rebuild or something?

    Google tells me that C++ doesn't support forward declaration of enums - could that be my problem?

    I've solved the problem temporarily by doing this at the top of the header file:
    namespace PlayerStances {
   enum {
      NumStances
   };
};
    Then just referring to PlayerStances::value whenever I need to.
