Thanks for taking a look. My hope is that (other than the minor performance hit) this change can only help avoid problems, because when you have a loop, the choice of starting class is fundamentally arbitrary. So if we assume the previous code, which only marked the first class in the loop as erroneous, was correct, then it must have been correct if it started with any other class in the loop (i.e., there is no "order"). Therefore, it must be correct to mark every class in the loop as erroneous 🤞
