Using __slots__ with a classic class is an error that does
not readily reveal itself. For Py2.3.1, I would like to
issue a warning, and for Py2.4, I would like to
raise an exception upon class creation:
>>> class A:
... __slots__ = 'abc' # Would otherwise pass silently
Traceback (most recent call last):
File "<stdin>", line 1, in ?
TypeError: PyClass_New: __slots__ only works with new-style classes
Do you guys agree?
