I'm trying to do automatic resolution of dependencies.

I've got this code in my routes.php file:

App::singleton('Client', function($app)
{
    $client = App::make('ClientInterface');
    $client = $client->getCurrent();
    return $client;
});
App::singleton('AlerterInterface', function($app)
{
    $replacers = array( new ItemReplacer );
    $messager = new SessionAlerter($prefix='alerter_machine', $replacers);
    return $messager;
});

Then, I've got this in a controller:

public function __construct( Shop\Product $product, AlerterInterface $alerter, Client $client )

Oddly, the AlerterInterface resolves, but the Client does not. and I get this error:

ReflectionException
Class Client does not exist

I can load the client just fine if I take it out of __construct's parameters and put it into the method, like this:

    $this->client = App::make('Client');

Any idea what's going on?
