I have that urge as well. That's because early in my CS study, we learned to
write correctness proofs for programs. And they only taught us how to do
that for while loops, since for loops etc are just syntactical sugar.

So in the back of my mind I still tend to think about setting up a
precondition, and loop with some invariant, until some guard condition isn't
true anymore.

But I only have it in Pascal and C, in Python it would be horrible :)
