Steps To Reproduce

The following component example should reproduce the error:

<?php

use Closure;
use Livewire\Volt\Component;

new class extends Component {
    //

    public function test(): Closure
    {
        return function () {
            echo "Hello World";
        };
    }
}; ?>

<div>
    Hello World
</div>

There is no namespace in those files, so you don't have to even include those imports on top.

@nunomaduro haha, typical me, making it more complicated than it needs to be. Thanks so much. :)
