Uncaught Exception when importing NamedTuple from typing #2753
Description
When importing NamedTuple from typing, I'm implementing
class A[T, U](NamedTuple)
data: T
error: U
class B[T](A[T, T])
def __new__(cls, data: T, error: T, message: str | None) -> Self:
return super().__new__(cls, data, error)
def __init__(self, data: T, error: T, message: str) -> None:
super().__init__()
<do something with message>Such that I can do
a, b = B(1, 2)
c, d = B(1, 2, "x")
assert a == c
assert c == d
However in my pre-commit hook I get:

This occurs both on 3.3.9 and 3.3.10.
Furthermore, when I import NamedTuple via a detour, e.g. from pandas.io.parsers.readers, the error does not occur.
