Rendering a Template example lists non-new use statement as "new"

[dangoodspeed]

In the example on
http://symfony.com/doc/current/book/page_creation.html#rendering-a-template-with-the-service-container

It says
// --> add this new use statement
use Symfony\Bundle\FrameworkBundle\Controller\Controller;

When it's not a new use statement. I'm a beginner reading through the docs, but I think it's the wrong use statement.

Actually, I would rather say that the previous examples extend the Controller class and thus have this use statement too soon.

The shown controller should only extends the base Symfony\Bundle\FrameworkBundle\Controller\Controller one in the "Rendering a Template (with the Service Container)" section IMO.

I suggest to remove any usage of the base Controller class before introducing the container on this book.

Took me a while to figure out what @ogizanagi meant (I'm a beginner), but yes I agree... removing all mentions of
use Symfony\Bundle\FrameworkBundle\Controller\Controller; and extends controller from the LuckyClass for the first five sample codes on the page_creation site would make the learning process a bit easier for those new to Symfony like myself.

@dangoodspeed : I've suggested those changes in the above PR. Thanks !
