Data/Object Punning might arise from *changes* in modelling, for  
example, lifting from a weaker representation (RDF or a RDBMS) or a  
legacy representation (e.g., Old Skool DC).

While it might be bad modelling, I find it difficult to argue that  
these situations shouldn't be expressible (e.g., as a transition  
point between one style of representation and another).

Cheers,
Bijan.
