To my eyes, this is genuinely harder to follow, despite its relative brevity:
while total != (total := total + term):
Does it even work? Perhaps if the goal is to stop when total is NaN, but otherwise?
Yes, it does, because the first "total" is looked up before the rebinding happens. It's 100% unambiguous to the compiler... but still pretty unclear to a human. And I think the multiple use of 'total' is to blame for that. So I agree with Tim that this particular example is better in longhand.
