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
