ctypes nested array constructor doesn't work with sequences

Using Python 3.7 and mypy 0.660 on the following code:

import ctypes

Quaternion = ctypes.c_int * 4
Pair = Quaternion * 2

quat = Quaternion(1, 2, 3, 4)
p = Pair((1, 2, 3, 4), (2, 3, 4, 5))

returns

$ mypy ctypes_nested.py 
ctypes_nested.py:7: error: Array constructor argument 1 of type "Tuple[builtins.int, builtins.int, builtins.int, builtins.int]" is not convertible to the array element type "ctypes.Array[ctypes.c_int]"
ctypes_nested.py:7: error: Array constructor argument 2 of type "Tuple[builtins.int, builtins.int, builtins.int, builtins.int]" is not convertible to the array element type "ctypes.Array[ctypes.c_int]"

even though at runtime this constructor works just fine. Of course, changing the constructor to Pair(Quaternion(1, 2, 3, 4), Quaternion(2, 3, 4, 5)) works just fine.

Reproduce el problema con el fragmento de Python y ctypes del informe y, después, rastrea cómo mypy gestiona los argumentos de los constructores de arrays de ctypes y los elementos de arrays anidados. Se considera terminado cuando Pair((1, 2, 3, 4), (2, 3, 4, 5)) pasa la comprobación de tipos sin errores, mientras que las formas existentes de Quaternion y de arrays anidados explícitos siguen siendo válidas.
