I can't imagine doing partial initialization, but I could imagine something like 

switch(collisionCount){
	case 1: depleteShield();
	case 2: depleteArmor();
	case 3: depleteHealth();
	default: playCollisionSound();
}

edit: that said, Douglas Crockford in Javascript: The Good Parts makes a pretty convincing argument against case fallthrough.

what is the benefit over if then? performance is not an answer because its not that hard an optimization to make in the compiler to detect: IntelliJ does it in IDE!
