I can appreciate the use case but not the semantics - you are not looking  
for an adapter but an implementation. I guess this is related to the  
IWhatever(object) approach which does the magic for you. I guess  
queryProvider(object, interface) would be a better spelling for that use  
case, which may be more general than I'm suggesting.
