PHP Errors obscured by framework messages

**Symfony version(s) affected**: 4.4.*

**Description**  
PHP syntax/parse errors are obscured by framework messages (i.e.: you can't see what the actual error was).

**How to reproduce**  
- Install the Symfony CLI
- Run: `composer create-project symfony/website-skeleton:^4.4 syntaxdemo` as shown in the setup guide (see: https://symfony.com/doc/4.4/setup.html )
- Create a file in `src/Controller` called `LuckyController.php` as shown in the next tutorial (https://symfony.com/doc/4.4/page_creation.html):

```php
<?php
namespace App\Controller;

use Symfony\Component\HttpFoundation\Response;

class LuckyController
{
    public function number()
    {
        $number = random_int(0, 100);

        return new Response(
            '<html><body>Lucky number: '.$number.'</body></html>'
        );
    }
}
```

- Create a syntax error in the file adding a `,` after the function parenthesis, that line should look like this: `public function number(),`
- Start the web server via: `symfony server:start` and navigate to the homepage.
- You'll see a Loader exception, not a parse/syntax error.

**Possible Solution**  
Not sure. Is this expected? It's a bit misleading.
