The following code fails with an infinite recursion in Jython 2.7. It works well on CPython. The problem is apparent in SQLAlchemy's SortedSet implementation. class TestSet(set): def difference_update(self, other): set.difference_update(self, other) return self __isub__ = difference_update a = TestSet('a') print a.difference_update(a) # inifinite recursion

class TestSet(set):

    def difference_update(self, other):
        set.difference_update(self, other)
        return self

    __isub__ = difference_update

a = TestSet('a')
print a.difference_update(a) # inifinite recursion
