PLE0237 false positive for slots literal concatenation

[airallergy]

I have a class, whose slots are formed by concatenating other literal tuples via RUF005 style. Below B is reported to violate PLE0237, which is a false positive, I also tried a few variants of B:

• C: If B is a subclass of any other class, PLE0237 seems to work fine
• D: If B slots has no other literal items, PLE0237 seems to work fine
• E: If B slots uses tuple concatenation, which violates RUF005, but PLE0237 seems to work fine

class A:
    pass


class B:
    names = ("x",)
    __slots__ = (*names, "a")

    def __init__(self) -> None:
        self.x = 1  # PLE0237: Attribute `x` is not defined in class's `__slots__`


class C(A):
    names = ("x",)
    __slots__ = (*names, "a")

    def __init__(self) -> None:
        self.x = 1


class D:
    names = ("x",)
    __slots__ = (*names,)

    def __init__(self) -> None:
        self.x = 1


class E:
    names = ("x",)
    __slots__ = names + ("a",)  # RUF005: Consider `(*names, "a")` instead of concatenation

    def __init__(self) -> None:
        self.x = 1

Thank you for opening this issue! I think we should ignore raising PLE0237 if __slots__ contain an unpacked argument.
