Error when type annotation shadows import "Invalid type ..."

[asottile]

import datetime
from typing import NamedTuple


class C(NamedTuple):
    datetime: datetime.datetime


print(C.__annotations__)

$ python t.py
OrderedDict([('datetime', <class 'datetime.datetime'>)])

$ mypy --version
mypy 0.650
$ mypy t.py
t.py:6: error: Invalid type "t.C.datetime"

I ended up renaming my attribute, though as far as I can tell this is legal code that mypy is rejecting
