At the risk of sounding like a breaking record, this is probably not true, mostly just because there isn’t really a way to use @pure correctly, ever. It doesn’t have well defined semantics. At some point we need a version of it that’s well-defined. The point people are trying to make here is that it’s best to avoid @pure because the compiler makes zero guarantees about what it means, so if you don’t 100% need it, you’re better off without it. Even if nothing breaks right now, future versions of Julia can and will break and crash your code. You might not care, but that’s the reason people try to get you to stop using it.
