Find the test case below:
----
from typing import NamedTuple
class Foo(NamedTuple):
alpha: int
index: int
----
This results in the following error when run through type-checking with mypy:
----
% mypy --version
mypy 0.620
% mypy go.py
go.py:5: error: Incompatible types in assignment (expression has type "int", base class "tuple" defined the type as "Callable[[Tuple[int, ...], Any, int, int], int]")
----
When I instantiate this class in the python interpreter, I have no problem accessing the "index" member, so I suspect this is a bug in the type checker.

> Perhaps this report should go on the mypy bug tracker rather than the Python language tracker. Agreed. It's up to the OP to file an issue there though (hence adding @campkeith back to the nosy list). |
