E0238 (invalid-slots)
Problematic code:
class Foo:
__slots__ = (bool,)
def __init__(self, bar):
self.bar = True
Correct code:
class Foo:
__slots__ = ('bar',)
def __init__(self, bar):
self.bar = True
Rationale:
Used when an invalid __slots__ is found in class. Only a string, an iterable
or a sequence is permitted.
