Which then would simply be the same behavior as properties when not 
promoted but declared in the class body instead:

```php

class Foo
{
     public $val = 'abc';
}

$redis_foo = serialize(new Foo());

$foo = unserialize($redis_foo);
var_dump($foo->val);
// string(3) "abc"

```

Right ?

What's the most disturbing in my opinion is that: `class Foo { public 
string $val = 'abc' }` and `class Foo { public function 
__construct(public string $val = 'abc' ) {}}` don't yield the same 
behavior at the time.
