@Fidget-Spinner Could you please review this PR?

@Fidget-Spinner Could you please review this PR?

The Python typing parts LGTM. But I need to do some revision for the C parts.

Fidget-Spinner · 2021-07-07T14:09:26Z

Hmm I wonder if it would be better if you split out the pure Python changes (like the nested __parameters__ search in typing) from the C+Python changes into a separate PR.

My reasoning follows that the Python changes can easily be backported. The C changes not so much and will require much more deliberation. What do you think Guido? @gvanrossum

gvanrossum · 2021-07-07T14:30:22Z

Agreed, this currently looks like two independent changes. See also the NEWS file.

uriyyo · 2021-07-07T14:54:31Z

@Fidget-Spinner @gvanrossum Thats makes sense. I will convert this PR into containing only typing fixes and will open another PR.

Yurii, sorry for the delay. Was a little busy. This LGTM. Thanks for submitting this PR.

BTW, it looks like the C changes to types.Union in the other PR won't make to 3.10 (we missed the beta 4 deadline). So we don't have to worry about backporting anymore.

uriyyo · 2021-07-12T10:50:20Z

Thanks for review, should we mention those changes at What's new section?

Fidget-Spinner · 2021-07-12T11:22:30Z

Thanks for review, should we mention those changes at What's new section?

Yes I was just thinking about that ;). I recommend we mention in whatsnew for 3.11 that union now supports nested type parameters.

uriyyo · 2021-07-12T12:10:52Z

Great, should it be done at separate PR?

Fidget-Spinner · 2021-07-12T12:18:00Z

Great, should it be done at separate PR?

Please do! I don't think the other C changes to fix typing.Annotated are whatsnew worthy. So you can start on it.

@gvanrossum Could you please review this PR?

gvanrossum

Great work! I will merge.

gvanrossum · 2021-07-17T03:35:09Z

@Fidget-Spinner Do you think this is worth a backport to 3.10? IIUC @serhiy-storchaka is backporting his types.Union improvements.

Fidget-Spinner · 2021-07-17T03:41:19Z

I think it's worth a backport but we can't since the PR adding __parameters__ #26980 was never backported.

gvanrossum · 2021-07-17T03:44:05Z

Never mind then. I guess that’s fine.

Fidget-Spinner · 2021-07-18T02:27:12Z

Thanks to Serhiy's Mass Cleanup, we can now backport this.

miss-islington · 2021-07-18T02:27:28Z

Thanks @uriyyo for the PR, and @gvanrossum for merging it 🌮🎉.. I'm working now to backport this PR to: 3.10.
