Description

We maintain a package that uses illuminate/collections and nothing else from Laravel. I wanted to test if it's compatible with Laravel 11, so I installed master. But now I get this error:

Fatal error: Trait "Illuminate\Support\Traits\Dumpable" not found in /var/www/html/vendor/illuminate/collections/Traits/EnumeratesValues.php on line 56

Related: #47122

Steps To Reproduce

1. Start an empty/basic Composer-project;
2. composer require "illuminate/collections:^11.0";
3. Try to use Collections;
4. See the error.
