Action helper for logging in ZF

/**
 * ZF Controller Action helper for logging. Assumes you have the log resource
 * setup in your bootstrap, but silently fails if it is not found.
 */
class My_Action_Helper_Log extends Zend_Controller_Action_Helper_Abstract
{
    /**
     * @var Zend_Log
     */
    protected $_log = null;

    public function init()
    {
        $this->_log = $this->getActionController()
                           ->getInvokeArg('bootstrap')
                           ->getResource('log');
    }

    public function log($message, $level = Zend_Log::DEBUG)
    {
        if ($this->_log == null) {
            return;
        }
        return $this->_log->log($message, $level);
    }

    public function __call($name, $arguments)
    {
        if ($this->_log == null) {
            return;
        }
        return $this->_log->__call($name, $arguments);
    }
}

Hmm, is calling __call directly on $this->_log evil?

Good god that's some hot zend action right there.

I honestly tend to prefer putting logging in a fat model layer and keeping my controllers thin.
