This PR was merged into the 4.4 branch. Discussion ---------- [DependencyInjection] Fix YAML example in "Defining a Service Locator" section Using this example in `v5.3.13` gives this error: ``` Symfony\Component\DependencyInjection\Definition::setArguments(): Argument #1 ($arguments) must be of type array, Symfony\Component\DependencyInjection\Argument\ServiceLocatorArgument given, called in /project/vendor/symfony/dependency-injection/Loader/YamlFileLoader.php on line 527 ``` I assume this is because `!service_locator` is the first constructor argument but it's passed as an array of constructor arguments, in which case the example is not right.
