I get your point. Inevitably someone sees “oh I can swap two values with 3x xor” and puts it in a real codebase. Write readable code. We probably don’t need to save the single word of memory in 2025.

Someone at work learned what a bitmap was and now uses them in dozens of golang structs as part of API bindings to know whether a field is set or not. It’s insane. Cool lower level tricks are neat but let’s not invent things that are difficult to understand or work with.
