Summary: (for D) make switch a loop

For a replacement for C why can't we make a switch statement loop?  We
can make switch less of a hack in the lanuage.

Make the switch loop be default so we trap switches without a default.

	switch (func(param)) {
	case (0):
		param = dosomething();
		continue;
	case (1):
		param = tryagain();
		continue;
	case (2):
		param = stillanother();
		continue;
	case (3):
	default:
		break;
	}

This way we have a DFA.  Maybe we can even dink the ':' after the
case.
