Not to mention that you can still use accessors/mutators with plain
attributes, and then store the actual value under a different name to
avoid the clash:

class FooX(Persistent):

    _bar = None

    def setBar(self, bar):
        self._bar = bar

    def getBar(self):
        return self._bar

    bar = property(getBar, setBar)
