    Why this fails - confusing

    please see the comments in code, can someone tell me why it works this way and fails the other way. i was trying to access the elements of the enum nested inside Logger class...
    class Logger
    	enum Level 
    		Debug, Warn, Error
    int main()
    	cout << Logger::Debug << endl; // Works.
    	cout << Logger::Level::Debug << endl; // Fails!
    	return 0;

    Perhaps because the first one is the proper way to do it?

    Because enums are not considered as namespaces, but is placed inside the owning class.
    Therefore the first is valid and the second is invalid.
