i believe his point (or i liked to read it such as) was more towards the responsibility of not messing up other programmers head, just because the language gives you the power to do so.

should the next programmer (usually =you+T) see the loop and think "oh, a loop" or "oh, a loop. and it uses the assignment of the each var to the conditional block... great, now i will have to go through the data we receive to make sure no element get's a value of zero"
