User generic with TypeVarTuple does not check for minimal type of arguments #99382
Description
The following code:
from typing import * T = TypeVar('T') T2 = TypeVar('T2') Ts = TypeVarTuple('Ts') class A(Generic[T, T2, *Ts]): x: List[T] y: List[T2] z: Tuple[*Ts] A[int]is executed without errors. It is expected to get an error because A requires at least two arguments.
Without TypeVarTuple you get helpful errors.
class B(Generic[T, T2]): pass B[int] B[int, str, bytes]TypeError: Too few arguments for <class '__main__.B'>; actual 1, expected 2 TypeError: Too many arguments for <class '__main__.B'>; actual 3, expected 2
