Zero-cost-abstraction Memes

Someone really out here defining maybe and later as preprocessor macros, then declaring a variable called maybe_later with a pointer. The "zero-cost abstraction" is just... procrastination as a language feature. It's like telling the compiler "yeah I'll figure out what this does eventually" but making it sound fancy. The pointer at the end suggests they might actually use it later, or maybe not. Schrödinger's variable declaration right here.
