/**
 * Object that represents the removal of array value while performing {@see Merger::merge()}.
 *
 * Usage example:
 *
 * ```php
 * $array1 = [
 *     'ids' => [
 *         1,
 *     ],
 *     'validDomains' => [
 *         'example.com',
 *         'www.example.com',
 *     ],
 * ];
 *
 * $array2 = [
 *     'ids' => [
 *         2,
 *     ],
 *     'validDomains' => new \Yiisoft\Composer\Config\Merger\Modifier\UnsetValue(),
 * ];
 *
 * $result = Merger::merge($array1, $array2);
 * ```
 *
 * The result will be
 *
 * ```php
 * [
 *     'ids' => [
 *         1,
 *         2,
 *     ],
 * ]
 * ```
