Oh look, it's the increment operator hierarchy in its natural habitat. While you're over there manually adding 2 to your variable like some kind of cave person ( i=i+2 ), I'm elegantly pre-incrementing and post-incrementing in a single expression ( ++i++ ). Sure, it's undefined behavior that will make senior devs cry blood and crash in production, but hey—my code is three characters shorter! Nothing says "technical superiority" like writing code that requires a compiler exorcism.
