terser input

class myClass extends EventTarget {
  static #happenedEvents = /*@__PURE__*/(() => {
    const set = new Set();
    window.addEventListener("event", e => myClass.#happenedEvents.add(e));
    return set;
  })();
  
  #classProperty = "Whole class doesn't get stuff removed now at all";
}

terser output or error

class e extends EventTarget{static#e=(()=>{const t=new Set;return window.addEventListener("event",(t=>e.#e.add(t))),t})();#t="Whole class doesn't get stuff removed now at all"}

Expected result

EventTarget

(Or ideally if something like #1443 is implemented, nothing)

It would also be really cool if a class declaration could be annotated with /*@__PURE__*/ somehow:

input:

/*@__PURE__*/class o {
  static {
    o.prototype.foo = 'bar'
  }
}

actual output:

class o{static{o.prototype.foo="bar"}}

expected output:

// nothing
