// Make me compile, without taking the macro out of the module! Scroll down for hints :)

mod macros {
    macro_rules! my_macro {
        () => {
            println!("Check out my macro!");
        };
    }
}

fn main() {
    my_macro!();
}

















































// In order to use a macro outside of its module, you need to do something
// special to the module to lift the macro out into its parent.








// The same trick also works on "extern crate" statements for crates that have
// exported macros, if you've seen any of those around.
