formatted print documentation uses the word "module" confusingly

> In line 43, #[allow(dead_code)] is an [attribute](https://doc.rust-lang.org/rust-by-example/attribute.html) which only applies to the module after it.

i don't think "module" is the right word here. line, maybe?
