Bug report

Hi if you declare a new Attribute in PHP 8 this error is thrown:

Constructor of class XX\XXX\Structs\Attribute\ArrayList has an unused parameter $structName.

In this case it is part of the standart and the paramter will be used in reflection.

Code snippet that reproduces the problem

<?php
declare(strict_types=1);

namespace XX\XXX\Structs\Attribute;

use Attribute;

#[Attribute(Attribute::TARGET_PROPERTY)]
final class ArrayList
{
    public function __construct(string $structName)
    {}
}

Expected output

The issue is reported incorrectly.

Did PHPStan help you today? Did it make you happy in any way?

Yes, every day!
