Hello Nikita,

for me this "maybe-of-type"-typehinting is a small progression in the right
direction.

But "Default values and nullability" would break existing code as you need
to add a default null at "design-time" (BC break):

<?php
class C {

    public $a; // public string $a = null;
    public $b; // public string $b = null;
    public function __construct($a, $b) {
        $this->a = $a;
        $this->b = $b;
    }

}

// test only a
$c = new C("foo", null);
var_dump($c->a === "foo");

// test only b
$c = new C(null, "foo");
var_dump($c->b === "foo");
?>
