[C++-sig] Wrapping method that returns const int& (boost::python)

[Stefan Seefeld]

  Panos, Erik,

the issue here is likely that Python's "int" objects are immutable. 
Therefore, you can't pass around ints by reference, only by-value. If 
the compiler is confused, perhaps you need to explicitly set a 
return-value policy that makes this clear ?
