However, to use Steve Yegge's example, say you're making a game, and you have a LightSource class, and a Weapon class, and now you want a glowing sword. :) Given, this sort of problem is far easier in ST than in java, because we have MessageNotUnderstood (I think that's what it's called), so you don't have to do as much stubbing.
