Rust will yell at you if you use specific magic numbers like these edit: yes, 0xCAFEBABE is a warning but 0xFEEDFACE is not: 3405691582 https://github.com/rust-lang/rust/blob/d0ea1d767925d53b2230e...

This is only for rustc, not for arbitrary rust programs.

That's a Code of Conduct violation. It's not the 90s anymore, there's no quarter for this type of thing in modern development teams. Rust's style checker even flags up the use problematic magic numbers.

That says all I need to know about the community.

But why?

It's a mystery, lost to the sands of time. IMO, it's highly unlikely anyone will ever discover why the maintainers of the Rust compiler decided to lint their codebase for a dozen or so magic numbers.

Kind of low-key hilarious that someone thought this was a serious enough issue to actually submit that code. I wonder if there is a written spec that helps to judge which integers should be considered "problematic" and which ones aren't.
