Decorators, that injection point can ask to have applied ad-hoc

[GoogleCodeExporter]

Let's say I want to support the following:

  @Inject RemoteService service;

or

  @Inject @ShortTimeout RemoteService service;

Currently this requires two different bindings and some ugly coding.  And
then if you want the short timeout for AnotherRemoteService you do it all
over again.  

Instead we could provide a way to independently bind the @ShortTimeout
annotation to a generic decorator such as

  interface Decorator<T> {
    T decorate(T t);
  }
  public class ShortTimeoutDecorator<T> implements Decorator<T> {
    public ShortTimeoutDecorator(Class<T> type, long time, TimeUnit unit) {
      ...
    }
    public T decorate(T t) {
      ...
    }
  }

Now you could just apply that to anything you want.

It looks like an extension (see comment #2) already implements this.
