Thanks to Jeff and John Fouhy . . . However, my question now is: can I treat Nodes sometimes the same and sometimes not? I want to treat Nodes whose cargo is the same the same everywhere *except* in a dictionary, because I want the user to be able to use LinkedList in a broader way than sets allow . . . In order to do this, I need my __hash__() method to treat Nodes differently than the rich comparison methods do. Is this a Bad Idea(tm) ?
The problem is, if you have two Nodes a and b where a == b, you will expect that for any dictionary d[a] == d[b]. If Node.__eq__() has different semantics than Node.__hash__() this expectation will not be correct.
