How to inject the @request into a service?

Question

When I try to inject the @request into any of my services, I get this exception:

ScopeWideningInjectionException: Scope Widening Injection detected:

The way I've found, and I'm sure it's probably not the best way (May not even be recommended), is to define the request service as synthetic.

Edit: Indeed, this is not recommended, because it disables the scope sanity checks. This thread contains a good explanation of why Symfony is throwing that exception: http://groups.google.com/group/symfony-devs/browse_thread/thread/a7207406c82ef07a/e2626c00f5cb9749

In your services.xml:

Per the docs, it's better if you place your service in the request scope, or just inject the service container.
