Factories and dependency injection

Last week I wrote about dependency injection anti-patterns in Drupal. These anti-patterns occur when your service's constructor has logic that interacts with the injected dependent services beyond assigning them to properties. These anti-patterns include creating a new object from a factory or retrieving an object from a stack. However, Symfony's service container supports defining services built from factories. This can streamline your code and follow best practices when using dependency injection.
