The progression from x += 1 (normal, acceptable) to x++ (meh, whatever) to x -= -1 (suddenly sophisticated) is the programming equivalent of putting on a tuxedo to take out the trash. Sure, you're technically subtracting a negative to increment, but you're also the kind of person who probably writes if (condition == true) unironically. It's mathematically correct, unnecessarily complex, and absolutely nobody asked for it—which makes it perfect code review material. Your teammates will either think you're a genius or question your life choices. Probably both.
