Subject: Re: [PHP-DEV] Constructor promoted property and default value
From: saki@sakiot.com (Saki Takamachi)

g ? In this case, your problem is not with promoted properties ?

If we specify it the way you say, the initial values =E2=80=8B=E2=80=8Bof th=
e constructor arguments will be available even when the constructor is not c=
alled.

```
class Foo
{
    public function __construct()
    {
    }
}

$foo =3D serialize(new Foo());=20
// save to redis

---- update ----

class Foo
{
    public function __construct(
        public $val =3D 'abc'
    ) {
    }
}

$foo =3D unserialize($redis_foo);
var_dump($foo->val);
// string(3) "abc"
// Doesn't it look like the constructor is being called?
```

Such behavior felt a little counterintuitive.

Regards.
