I wonder why `invalidate_inner_signals` is placed in a separate effect instead of calling it inside the selector's setter, similarly to how it was done in Svelte 4: ```js function select_change_handler()...

`setup_select_synchronization` is such, basically, since the very beginning of Svelte 5 and I'm not sure why. But I'd explore moving the logic inside the setter in hope we can recreate...

@KieranP your Svelte 4 example seems to be oversimplified and missing something important - the `$:` blocks also run during the component initialization. Also, unlike `$:`, `$effect` doesn't run on...

In a case like your one, you expect the execution order of subscribers be * store1subscriber1 * store1subscriber2 * store2subscriber1 * store2subscriber2 * store2subscriber3 * store1subscriber3 * store1subscriber4 but it...

You need to make the symbol optional `{ [stateKey]?: unknown }` but the real problem is that you cannot rid of the marker: ```js let a = $state(5); // StateProxy...

It should be recursive (it's possible) but only for POJOs. In TS, a class instance and a POJO with the same fields are the same thing, aren't they?
