Our internal organization doesn't define our external interface. +Here we have a `pub use` for each function we want to bring into the +`japanese` scope. We could alternatively use the wildcard syntax to include +everything from `greetings` into the current scope: `pub use self::greetings::*`. + Also, note that we `pub use`d before we declared our `mod`s. Rust requires that `use` declarations go first. |
