How would you expect the following code to behave:
class Base(object):
def __init__(self): self.x = 23
class Derived(Base):
__slots__ = 'y',
? I would expect it to work (as it does in Python), therefore I think
it's fit and proper that __slots__ "breaks with inheritance", meaning it
basically has no effect unless every class in the inheritance DAG has
slots.

Since the only benefit of __slots__ is saving a few bytes per instance,
it's not worth the bother unless there are many instances -- so, the
answer is 'no'.
