The problem is that while you don't want to know you end-up having to. As soon as you hit the limitations you have to workaround it. As soon as what you are doing becomes expensive for reasons you ignored before, you have to go back and rewrite. The only thing is that because it's a Blackbox, you also have to guess and poke it until it does the thing you want.
