Symfony: Inject object (not service) to service constructor
===

In the definition of my services, I'd like to pass as a service argument constructor an object not a service.

From config.yml:

    services:
      acme.services.exampleservice:
        class:  Acme\ExampleBundle\Services\ExampleService
        arguments: 
            entityManager: "@doctrine.orm.entity_manager"
            httpClient: \Example\Http\Client\Client

Note the `httpClient` argument. This must be an instance of the `\Example\Http\Client\Client` class.

The above does not work - the string "\Example\Http\Client\Client" is passed as the `httpClient` argument to the service.

What is the syntax for achieving the above by means of passing an instance of `\Example\Http\Client\Client` to the service constructor?
