     It occurs to me that there is, sort of:

	final boolean once;
	switch (someEnumVar) {
	case E1:
	   once = true;
	   if (...) {
	      ...; return;
	   } else if (...) {
	      ...; throw ...;
	   } else {
	      ...; continue; // enclosing loop
	   }
	case E2:
	   once = true; // compiler complains if fall-through possible
	    ...
	case E3:
	   once = true; // ditto
	   ...
	}

IMHO, this particular cure is a lot worse than the disease.
