2 Checks for usage of `write!()` / `writeln()!` which can be
3 replaced with `(e)print!()` / `(e)println!()`
6 Using `(e)println! is clearer and more concise
10 writeln!(&mut std::io::stderr(), "foo: {:?}", bar).unwrap();
11 writeln!(&mut std::io::stdout(), "foo: {:?}", bar).unwrap();
16 eprintln!("foo: {:?}", bar);
17 println!("foo: {:?}", bar);
