Code

class C{
    #prop = 1;
    method() {
        const { #prop/*1*/: prop } = this;
        ({ #prop/*2*/: this.#prop } = this);
    }
}

Expected behavior:

Error at /*1*/ and /*2*/ since this syntax is not (yet) allowed. tc39/proposal-class-fields#4

Thanks to Titian Cernicova-Dragomir (@dragomirtitian) for pointing this out.

Actual behavior:

No error.
