Bug description:Incorrect constructor promotion
Description:
------------
Confusing with constructor promostion result. I got warning where I
shouldn't, as far I undestand the RFC.
snippet: https://3v4l.org/SKTie
Test script:
---------------
<?php
class A {
public function __construct(
public $a = 1
) {}
}
class B extends A {
public function __construct(
public string $b = 'hello'
) {}
}
$b = new B();
var_dump($b->a, $b->b);
Expected result:
----------------
As far I understand it's the same code after deshugaring w/o any
warnings with output
```
NULL
string(5) "hello"
```
snippet: https://3v4l.org/HM5s0
```php
<?php
class A {
public function __construct(
public $a = 1
) {}
}
class B extends A {
public function __construct(
public string $b = 'hello'
) {}
}
$b = new B();
var_dump($b->a, $b->b);
```
Actual result:
--------------
Warning: Undefined property: B::$a in /in/SKTie on line 16
NULL
string(5) "hello"
