Thus I leave a comment.

But seriously… your example of looping to calculate a total is OK if there’s no way to exit the loop prematurely (just as calculating global_revenue is safe as long as no bozo sticks a line of code in the middle). But what if you leave the loop early due to an ON ERROR statement?

The real solution is to have a temporary variable (e.g. accumulate_total) in the loop that is discarded after the calculation.

I freely admit that I’m frequently too lazy to follow my own advice.
