For instance, in Java this would be done like this: outerloop: for (int i=0; i<10; i++) for (int j=0; j<10; j++) if (condition_met) break outerloop; Do

As you may know, only interfaces and MarshalByRefObjects may be marshalled or intercepted. I'm developing my own RealProxy (for the typical logging-scenario) and I want to write a generic method which has an interface as parameter and returns a new __TransparentProxy.
