Ah, I don't like the code increase and the complexity... Hope there's a better idea.

[dai-shi]

I'm not even sure if it's correctly implemented. test cases may help, but it feels like a bad design.

[dai-shi]

It's a bit better now. The code isn't very explicit compared to context, but it's less complicated I suppose.

[dmaskasky]

Any concern with store.unstable_derive being confused with jotai-derive? https://github.com/pmndrs/jotai/pull/2656

[dai-shi]

I think it's fine.

[dai-shi]

@dmaskasky I will merge this. It doesn't mean we finalize it yet. We hope it though.

[dmaskasky]

Ok, makes sense. In a few weeks I will try again to make this work. I might need some more help though.
