If the arguments are really random, how can the function work? They
can't just be chosen at random. As to their number, it depends on how
many arguments the function needs. Regarding local variables, you know 
very well that C can have external variables. I think that no one is going
to win this argument against you because you're going to come up with
contrived rebuttals no matter what anyone says. If goto's have a place
in C, you haven't made a "case" for them.

/* Really: */
	case whatever:
		special-code...;
		goto common;
/* Is no clearer than: */
	case whatever:
		special-code...;
		common();
		break;
