Use of Annotations with Factories

I have been reading and re-reading the wiki as well as the code comments, but I am still very unclear on how Annotations can be used with factory injection (`std::function>`), if that it even supported. The comment on `bind()` in component.h says,

` * All these cases support annotated injection, just wrap I and/or C in fruit::Annotated<> if desired. For example:`

The example only shows the simple case. How does it work with factories?
