Weird behavior with uninitialized typed properties and __set/__get

Weird behavior with uninitialized typed properties and __set/__get
Seems calling a constructor is triggering __set magic for uninitialized typed properties. So it does not matter the property is public or private/protected.
I suppose the problem is __set/__get called before __construct when a type is given to a property. Also I if remove __get then I get object(acme\Options)#1 (1) { ["stack"]=> array(1) { ["stack"]=> array(1) { ["one"]=> int(1) } } }.

Uninitialized typed properties
While throwing when try to access to any uninitialized typed property (eg: $o->x == null),
the codes below are just causing notice.
BTW, error message is so weird. We were expecting something like this;
View uninitialized stuff
// Java
class Foo { Integer i; }
class Test {
public static void main(String args[]) {
System.out.println(new Foo().i == null);
}
}
// JavaScript
View nö.php
<?php
// ok, cos converted to ?int = null, right?
function foo(int $i = null) {}
// ok, all ok, right?
$a = new class {
public $i;
public function check(): bool {
return ($this->i != null);
}
