`phrases::japanese::farewells::goodbye()`. 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.
