I'm not dead sure about that, but I heard recently that python's been
optimized for that behaviour. That means: using += is almost as fast
as joining list. Besides, "+=" is more obvious than the other choice
and since performance is not a problem until it's a problem, I'd
rather use it. Anyway: I wouldn't pick it for an interview question.
