Bug Report

Subject	Details
Rector version	e.g. v0.7.55
Installed as	composer dependency

So I am not sure whether it’s a parser issue or a rector issue, but I ran vendor/bin/rector process app -v (I thought -v is verbose but it’s not the case I think)

with this config (rector.php in root folder)

<?php

declare(strict_types=1);

use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;
return static function (ContainerConfigurator $containerConfigurator): void {
    $parameters = $containerConfigurator->parameters();
    $parameters->set('php_version_features', '7.4');
};

I get this error

Rector v0.7.55
Config file: rector.php

If I remove the -v modifier, I get this instead

(the notice is getting out many times)

After these, I get some errrors such as

Or also

Minimal PHP Code Causing Issue

<?php

namespace App\Console\Commands;

class Command {}

class GenerateAllModels extends Command
{
}

Expected Behaviour

I can’t show you the demo permalink because I got this warning
