I'm probably being stupid, but surely if you pass by non-const 
reference then you *expect* it to change?

Of course, modified in C++ is not modified in Python where basic 
types are immutable. But it does seem a reasonable approximation that 
as a default, the python parameter is rebound to the output value for 
integral types.
