Using eval with 'super'/'super()' in arrow function within the class should not lead to Syntax error:

const testValue  = 'test-value';

class A {
    constructor() {
        this.idValue = testValue;
    }
};

class B extends A {
  constructor (beforeSuper) {
      var arrow = () => eval('(() => super())()');
      arrow();
  }
};

let b = new B();
b.idValue == testValue; //true
