Right. That's my fix. I was probing for discussions not solutions. I'm inclined 
to say that if a class has Singleton on it, it should be honored. However, this 
impacts existing applications that are attempting to override the Singleton 
annotation via a Provider. But I would hope that isn't common.

I've honestly never looked at the code, but I would assume that looking for 
annotations on instances returned from Providers would be simple enough.
