+1 to always returning a copy. If *anything* is returned, I would expect it to be a copy. Note that one convention that I have observed in python is to return None if an object is modified by a method. You see this in the sort() method for lists, for example. We have also tried to follow this convention in the graph theory code (and we've had this discussion before when contemplating changing the graph theory code).
