PHP League Plates $e() trick

Question

So at one point I swore I saw a League Plates extension that mapped $this->escape() to $e(). IE:

<label><?= $e($args['label'])?></label>

vs

<label><?= $this->e($args['label'])?></label>

but when I finally decided to try it, I couldn't find it. So I ended up hacking up the following:

    class EnginePlus extends Engine {
        public function render($name, array $data = array())
        {  
            $template = $this->make($name);
            $data['e'] = function($string, $functions = null) use ($template) {
                return $template->escape($string, $functions);
            };

            return $template->render($data);
        }
    }

Because, typing and reading those 6 extra characters was just killing me. ;-) Was there an easier or better way to do this?
