I think it's good for the Python syntax to deviate from the C++  
insofar as python is not C++. Specifically, anytime a python object  
has any references to it, that object's memory should never be  
released. Having live python objects which are just raw pointers and  
not smart pointers violates this contract, and should be eschewed  
whenever possible, IMO, even at the cost of making the code look a  
bit different than it would under C++.
