Case
====

I am playing around on a laravel project to see if i can use closures for my implementation of a sorting interface, and i noticed that when i `dd()` my closure, it also shows the class in which the closure was created as a property.

Minimised Code
==============

```
// in my Order model class, i have a function that will return a closure
public static function defaultSortFunction(){
    $sortColumn = property_exists(self::class,'defaultSortingColumn') ? self::$defaultSortingColumn : 'created_at';

    return function($p,$n)use($sortColumn){
        return $p->$sortColumn <=> $n->$sortColumn;
    };
}

```

```
// in one of my controller I use for testing, I added these 2 methods for testing
public function index(){
    $sortFunction = Order::defaultSortFunction();
    $this->someOtherFunction($sortFunction);
    return 'done';
}

private function someOtherFunction($fn){
    dd($fn);

    // $scopeModel = get_class($fn); => Closure

    // example of how I can use this value later
    // $scopeModel::take(10)->get()->sort($fn);
}

```

The result of the `dd()` inside `someOtherFunction()`:

```
^ Closure($p, $n) {#1308 ▼
  class: "App\Order"
  use: {▼
    $sortColumn: "created_at"
  }
}

```

Question
========

From the result of the `dd()` it shows that the closure has a property that shows that it was defined in the class `App\Order`. **Is there any way to access this value**?

I have tried `get_class($fn)` but as expected it gives `"Closure"`, and if i did `$fn->class` it gives an error saying `Closure object cannot have properties`.
