Hi guys!

Take the following class:

class ProductRepository
{
    private $client;
    private $logger;

    public function __construct(Client $client, LoggerInterface $logger)
    {
        $this->client = $client;
        $this->logger = $logger;
    }
}

Since LoggerInterface can't be injected yet (we're waiting on a MonologBundle tag), I wired it like this:

services:
    product_repository:
        class: AppBundle\Repository\ProductRepository
        autowire: true
        arguments:
            1: '@logger'

Sure, it's weird to have the "1" in there, but I thought it would work. It almost did, but it reversed the arguments. In the cached container, this becomes:

new ProductRepository($this->get('logger'), $this->get('api_client'));

In YAML, I believe this is the only way to set one specific argument, without specifying all of them, and it looks like a bug :).

Especially because non-services can't be autowired yet, this probably the biggest issue left with autowiring (along with not being able to globally map a class/interface to a specific service id).

Thanks!
