In Rust println!() is a macro and it's just as readable as stdout print commands in other languages, in fact it's simpler than some. Macros can be great if used to overcome a syntactical limitation, in which case they can make the code more readable and compact. If it introduces barriers to reading the code it's not a good macro, and maybe unnecessary.
