However, I=E2=80=99m just realising that omitting `public` in =
declarations like `public $a` and `public int $b` is probably not a good =
idea, because it is incompatible with constructor property promotion, as =
`function __construct(public int $b) { }`, and `function __construct(int =
$b) { }` have different meanings.
