Otherwise, one will have to get rid /by hand/ of all the `__cmp__` methods everywhere, that will become obsolete in python3.
Don't confuse the cmp() function with __cmp__() methods! Getting rid of cmp() and getting rid of __cmp__() are a priori different issues.
An easy but ugly solution for both would be to simply keep supporting cmp() and __cmp__() in Python 3.
For cmp(), we could try to "port" it to Python 3. We could write a cmp() function which behaves just like the cmp() from Python 2.
For __cmp__(), we could support it at least in the coercion model (i.e. anything inheriting from Element).
