I rewrote your code, but it is useless... value does nothing - maybe replace with console.log

The rewrite is incorrect, you declare a new variable inside the scope of the function, it's not the same value from the layout, so the code run, but it has no effect in the component C.svelte

---

The value from a snippet instruction seem to be immutable, similar to getContext/setContext

If it's the case, then maybe the documentation should indicate this limitation, and maybe the same workaround as getContext

---

So, if, instead of a simple value, a plain old store is used, then the code work as expected (as far as I understand the goal of this code) (See my version with store, I add a <fieldset> that contains the content of value to visualize the changes)
