Description

The following code is a bug since the introduction of anonymous classes in PHP 7.0:

https://3v4l.org/0OTZ9#v7.0.0 // for reference
https://3v4l.org/0OTZ9#v8.3.1

<?php

$anonymous = new class(){};

echo get_class($anonymous).': now you see me...';

trigger_error(
    get_class($anonymous).' ...now you don\'t!', 
    E_USER_ERROR
);

Note: it doesn't matter if get_class or $anonymous::class is used. As soon as it is an anonymous class name, it fails.

It also fails when throwing an Exception:

<?php

$anonymous = new class(){};

echo get_class($anonymous).': now you see me...';

throw new Exception(
    get_class($anonymous).' ...now you don\'t!', 
    E_USER_ERROR
);

Resulted in this output:

class@anonymous/in/0OTZ9:3$0: now you see me...
Fatal error: class@anonymous in /in/0OTZ9 on line 7

Process exited with code 255.

But I expected this output instead:

class@anonymous/in/0OTZ9:3$0: now you see me...
Fatal error: class@anonymous ... now you don't in /in/0OTZ9 on line 7

Process exited with code 255.
