Touche. Another advantage a namedtuple has is that it can expand out of the box
- i.e., can write something like
> for x, y, z in namedtuple_list:
without any list comprehensions.
Can we bring those advantages into the dataclass while also preserving
pavel-lexyr added the comment:
Most of the differences are direct upgrades added in the dataclass module.
Deprecating dataclass in favour of nametuple would be counterproductive, I
agree - what about vice versa?

As of right now, two very similar constructions for making a lightweight
dataclass exist in Python.
collections.namedtuple is one of them. dataclasses.dataclass is

There is a core part of the `takedowhile` proposal's use case that I am having
trouble envisioning via the alternative `before_and_after` proposal. If the
`after` part of the iterator the user does not engage with, the transitional
elements will be
pavel-lexyr added the comment:
I see. If the syntax allows for better ways to do it now, perhaps a move
towards deprecation would be a better idea then? This would agree with the Zen.
Also, please elaborate more on the generator-based solutions you have in mind.
The suggestion stems from a
New submission from pavel-lexyr :
As described in the documentation, itertools.takewhile() returns all the
elements until the first one that does not match the provided criterion. In
case of a destructive iterator, or one with side effects, not yielding an
element downstream may render

Python's native HTTP server (http.server module) has special code to allow it
to detect and bind to IPv6 addresses when called as a CLI tool. As of right
now, the code is in private functions. Those are not intended to be called by
