    }
}

Traditionally, Symfony services were configured in XML or YAML files. This creates a bit of a disconnect between your code and the configuration. In modern Symfony, we can use native PHP attributes to configure services. This allows us to keep our service configuration right in our code as native PHP metadata, which is pretty cool! Let's dive into these Dependency Injection attributes in the context of a fun example.
