Something, something, get off my lawn? Actually I wasn't getting paid to write C back in 1989, but I definitely did write C in the era when ANSI C wouldn't have been generally accepted.
Immutable variables are a good idea (indeed I agree with Rust's choice to make variables immutable by default), but, they're not constants, and so this is an unnecessary confusion.
