solid/reactivity - array destructing

[obecny]

Have this code, why is it causing a warning about solid/reactivity (check constructor). Is the warning invalid ? As for this case imho it should not cause it. In the end it is working as expected.

import { render } from "solid-js/web";
import { Accessor, createEffect, createSignal, Setter } from "solid-js";

class Foo {
  public a: Accessor<string>;
  private _setA: Setter<string>;
  
  constructor() {
    // warning solid/reactivity
    [this.a, this._setA] = createSignal('no value');
  }

  public setA(value: number): void {
    this._setA(`value: ${value}`);
  }
}

function Counter() {
  const [count, setCount] = createSignal(0);
  const increment = () => setCount(count() + 1);
  const foo1 = new Foo();

  createEffect(() => {
    foo1.setA(count());
  });

  return (
    <button type="button" onClick={increment}>
      {count()} - {foo1.a()}
    </button>
  );
}

render(() => <Counter />, document.getElementById("app")!);
