NamedTuple triggered mypy error inside a class #7531

@yihengli

Description

@yihengli
from typing import NamedTuple


class A:
    def __init__(self) -> None:
        self.tuple2 = NamedTuple('x', [('y', str), ('z', bool)])

    def run2(self) -> NamedTuple:
        return self.tuple2(y='y', z=True)


print(A().run2())

The script will trigger "NamedTuple" not callable mypy(error), not sure if this is as expected

Tested with Python37 and mypy==0.701
