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.

L’issue ne nomme aucun fichier source ni aucun test. Commencez par reproduire l’erreur de syntaxe avec l’exemple TypeScript 2.2.1 et examinez la discussion existante sur les getters optionnels. Il faut qu’un comportement soit défini pour get fullName?() et qu’une validation corresponde à cette décision.
