Thanks Dave,
        The member functions are returning non-const references to classes which are
in container members of the owning class. I'm developing a realtime
interactive music extension for python (for now Midi, and later audio). The
functions return things like a reference to a class representing a Midi out
port. 
        
        I don't think I need your reference counting code as yet, because these
objects aren't very dynamic.

        I would have had a HELL of a time wrapping my code with swig, so thanks VERY
much.

To what is the reference referring? If it refers to an object owned by one
of the arguments to the function you're wrapping (including "this", if it's
a member function) I could give you a way to return the non-const reference
safely; it would work by managing a reference count on the owning object. I
have offered this to several people in the past, but demand has not been
great so far.
