ofMany() uses the calling function's name as the join alias. On PHP 8.4 a closure defined outside a class is named like {closure:/var/www/routes/web.php:12}, and the dot breaks the query:

User::resolveRelationUsing('bestPost', function ($user) {
    return $user->hasOne(Post::class)->ofMany('score', 'max');
});

$user->bestPost; // syntax error near "."

On PHP 8.3 closures were just named {closure}, so this used to work.

Now the related table name is used when the guessed name is a closure.
