Cannot Optionalize Class Getters

TypeScript Version: 2.2.1

Code

class Person {
  firstName: string;
  lastName: string;

  get fullName?() {
    return this.firstName + ' ' + this.lastName;
  }
}

Expected behavior:

Since fullName is optional the following should work:

const Me: Person = {
  firstName: 'Foo',
  lastName: 'Bar'
}

Actual behavior:

A syntax error occurs on this line get fullName?() {

I'm not sure if omitting the ability to optionalize getters was by design or not. If it was by design, I'd love to know the reasoning behind it.

La issue non indica alcun file sorgente né alcun test. Inizia riproducendo l’errore di sintassi con l’esempio di TypeScript 2.2.1 e rivedi la discussione esistente sui getter opzionali. Sono necessari un comportamento definito per get fullName?() e una validazione coerente con tale decisione.
