==================================================
Feature: #101396 - Let Extbase handle native enums
==================================================

See :issue:`101396`

Description
===========

With PHP 8.1, native support for `enums`_ has been introduced. This is quite handy
if a database field has a specific set of values which can be represented by a
PHP enum.

..  _enums: https://www.php.net/manual/en/language.types.enumerations.php

It is now possible to use backed enums in entities like this:

..  code-block:: php

    <?php

    declare(strict_types=1);

    namespace MyVendor\MyExtension\Domain\Model\Enum;

    enum Level: string
    {
        case INFO = 'info';
        case ERROR = 'error';
    }

..  code-block:: php

    <?php

    declare(strict_types=1);

    namespace MyVendor\MyExtension\Domain\Model;

    use TYPO3\CMS\Extbase\DomainObject\AbstractEntity;

    class LogEntry extends AbstractEntity
    {
        protected Enum\Level $level;
    }

Impact
======

To implement enums, it is no longer necessary to extend the now deprecated TYPO3
Core class :php:`\TYPO3\CMS\Core\Type\Enumeration`.
