The `macros4.rs` challenge can automatically be solved by rustfmt without the user noticing. Adding `#[rustfmt::skip]` above the `macro_rules!` line fixes this issue. |

Macros
Rust's macro system is very powerful, but also kind of difficult to wrap your head around. We're not going to teach you how to write your own fully-featured macros. Instead, we'll show you how to use and create them.
If you'd like to learn more about writing your own macros, the macrokata project has a similar style of exercises to Rustlings, but is all about learning to write Macros.
