Before You File a Bug Report Please Confirm You Have Done The Following...

• I'm using eslint-plugin-svelte. (*.svelte file linting does not work with the parser alone. You should also use eslint-plugin-svelte with it.)
• I'm sure the problem is a parser problem. (If you are not sure, search for the issue in eslint-plugin-svelte repo and open the issue in eslint-plugin-svelte repo if there is no solution.
• I have tried restarting my IDE and the issue persists.
• I have updated to the latest version of the packages.

What version of ESLint are you using?

9.18.0

What version of eslint-plugin-svelte and svelte-eslint-parser are you using?

• svelte-eslint-parser@1.0.0-next.11
• eslint-plugin-svelte@3.0.0-next.14

What did you do?

<!-- Paste your configuration here -->
import js from "@eslint/js";
import sveltePlugin from "eslint-plugin-svelte";
import svelteParser from "svelte-eslint-parser";
export default [
  js.configs.recommended,
  ...sveltePlugin.configs["flat/recommended"],
  {
    rules: {
      "no-sequences": "error",
    }
  },
  {
    files: ["**/*.svelte.js", "*.svelte.js"],
    languageOptions: {
      parser: svelteParser,
    }
  },
];

<script lang="ts">
  let value = $state('');
</script>

<input bind:value={
	() => value,
	(v) => value = v.toLowerCase()}

Additional comments

bind:property={get, set} seems to be a feature added in Svelte 5.9.0.
https://svelte.dev/docs/svelte/bind#Function-bindings

Since this is not a sequence expression, I think it requires AST changes.
