title: ES6 Destructuring in Class constructor
body: <p>This may sound ridiculous but bear with me. I wonder if there is support on the language level to destructure object into class properties in constructor, e.g.</p>
  
  <pre><code>class Human {
      // normally
      constructor({ firstname, lastname }) {
          this.firstname = firstname;
          this.lastname = lastname;
          this.fullname = `${this.firstname} ${this.lastname}`;
      }
  
      // is this possible?
      // it doesn't have to be an assignment for `this`, just something
      // to assign a lot of properties in one statement
      constructor(human) {
          this = { firstname, lastname };
          this.fullname = `${this.firstname} ${this.lastname}`;
      }
  }
  </code></pre>
