Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.

Hi, I'd suggest looking at the devguide for the pull request tutorial.

A number of things I'd like you to change here:

• Please move the test to somewhere in the existing dataclass tests.
• This needs a blurb entry per the bot, but also needs a whatsnew entry for 3.14.
• The title should be in a gh-NNNN: quick summary format.

The test is failing, FYI!

Also, please give this a better title. I didn’t notice it in my inbox. Thanks!

Still needs a better title, I just copied the one from the issue.
