New submission from Erik Montnemery :
typing.NamedTuple behaves in surprising ways when it has default arguments
which lack type annotations:
>>> from typing import NamedTuple
>>> class MyTuple(NamedTuple):
... a = 1000
...
>>> tmp = MyTuple()
>>> tm
Erik Montnemery added the comment:
I think elaborating in the documentation that only annotated attributes make it
to the underlying namedtuple() would be helpful, it's not obvious that they are
instead just class attributes.
