I think you're overreacting a bit, Soren. In fact, even if you did look, no law does prohibit reading, only copying. If you inspect a m-file from Matlab to learn just the trick, and don't actually memorize and reproduce any code, it's technically still legal. But in any case, you said you didn't look, so you didn't look and that settles it.
