Zend framework 2: How to use view helper in other view helper

Is it possible to use view helper in another view helper? We have to view helpers:

HelpMe1

use Zend\View\Helper\AbstractHelper;

class HelpMe1 extends AbstractHelper
{

    public function __invoke($arg)
    {
        return $arg;
    }
}

HelpMe2

use PathTo\HelpMe1;
use Zend\View\Helper\AbstractHelper;

class HelpMe2 extends AbstractHelper
{

    public function __invoke()
    {
        return '<p>' . new HelpMe1('Text') . '</p>';
    }
}

If this is possible what it the base practice for that?
