I would agree.

As far as I remember, you ask the object in question to give you a 
specific interface, and the object returns an instance that is 
guaranteed to implement the interface (could be the object itsself or a 
wrapper). When this fails, maybe the interface itsself knows how to 
wrap around the object and can create such one.
