Code

class C{
    #prop = 1;
    method() {
        const { #prop: prop } = this;
        ({ #prop: this.#prop } = this);
    }
}

Expected behavior:

No error as the property is read by the destructuring binding and the destructuring assignment.

Actual behavior:

'#prop' is declared but its value is never read.(6133)
