	/**
	 * Filters whether the fatal error handler is enabled.
	 *
	 * **Important:** This filter runs before it can be used by plugins. It cannot
	 * be used by plugins, mu-plugins, or themes. To use this filter you must define
	 * a `$wp_filter` global before WordPress loads, usually in `wp-config.php`.
	 *
	 * Example:
	 *
	 *     $GLOBALS['wp_filter'] = array(
	 *         'wp_fatal_error_handler_enabled' => array(
	 *             10 => array(
	 *                 array(
	 *                     'accepted_args' => 0,
	 *                     'function'      => function() {
	 *                         return false;
	 *                     },
	 *                 ),
	 *             ),
	 *         ),
	 *     );
	 *
	 * Alternatively you can use the `WP_DISABLE_FATAL_ERROR_HANDLER` constant.
	 *
	 * @since 5.2.0
	 *
	 * @param bool $enabled True if the fatal error handler is enabled, false otherwise.
