That's what I tried and what worked:
public @interface MakeLoggable {}
public interface Loggable{
Logger getLogger();
}
public aspect AutoLogging {
declare parents: (@MakeLoggable *) implements Loggable;
public Logger Loggable.mLogger;
public Logger Loggable.getLogger()
{
return mLogger; // okay, lazy initialization here
}
}

However, if I switch the mLogger injection to
public static Logger Loggable.mLogger;
I get an error that I cannot introduce a static member into an interface.
So, can I get this done at all? If so, how?
