I just stumbled across this issue trying to resolve this:

While this fails:

foo: int
bar: str

Okay, I found the solution. Not using super() works:
from typing import NamedTuple
class Spamm(NamedTuple):
foo: int
bar: str
def __getitem__(self, index_or_key):
if isinstance(index_or_key, str):
try
Richard Neumann added the comment:
Thank you all for your input.
I had a look at aforementioned discussion and learned something new.
So I tried to implement the dict data model by implementing keys() and
__getitem__() accordingly:
from typing import NamedTuple
class Spamm(NamedTuple
Richard Neumann added the comment:
I could have sworn, that this worked before, but it was obviously me being
tired at the end of the work day.
Thanks for pointing this out and sorry for the noise.

When sublassing the built-in list, the invocation of super().__new__ will
unexpectedly expand the passed arguments:
class MyTuple(tuple):
def __new__(cls, *items):
print(cls, items)
return super().__new__(cls, items)

I have use cases in which I use named tuples to represent data sets, e.g:

"""Basic statistics response packet."""

Richard Neumann added the comment:
Awesome, I didn't know that.
I tried it without the parens and it gave me a SyntaxError.
This can be closed then as it's obviously already implemented.
Let's get to refactoring.

Currently only plain strings can be used as docstrings, such as:

For dynamic class generation, it would be useful to allow format strings as
docstrings as well:

Apologies as I'm not super-familiar with Latin1 or how Python refers to Latin1,
but it seems a little odd to even call it Latin1. It can be decoded as Latin1,
but it can contain every possible byte, including 0x7f through 0x9f, which
aren't really Latin1

Wow, that's a great catch with bytearray on py2. Protocols 0-2 are all actually
supposed to work with python 2, and I was using 0 from Py3 as it's the default
for Py2, and what I want to use during a short transition where both Py3 and
Py2 are operating

The docs for pickle, in python 2, say that the default pickle protocol, 0,
produces ASCII. In the python 3 docs, this has changed to "human-readable".
While the pickle output with protocol 0 loads fine in python2, it is definitely
not huma

I'm not sure whether the property method should be changed.
I think it'd be more appropriate to raise a value error upon __init__ in this
case as it is done with other checks.

Currently, iterating over dict_items will yield plain tuples, where the first

This has some disadvantages when e.g. sorting dict items by value and key:

The class subprocess.CompletedProcess is currently lacking a __bool__() method.
