PHP Memcached isset

Any idea if PHP's memcached module supports some kind of isset() method?

Following case:

Memcached::set('foo', false);

if(Memcached::get('foo') === false) {
        // Set or not set?
}

according to the documentation

if($memcached->get('var') === false && $memcached->getResultCode() == Memcached::RES_NOTFOUND){
   //not set
}

You can of course extend the Memcached object to include it, however, you can't ask if it's set without getting it (some overhead on larger values):

class YourMemcached extends Memcached {
    function var_isset($var){
       return $this->get($var)!==false || $this->getResultCode() != Memcached::RES_NOTFOUND;
    }
}

(you can't use isset as a method name as it's a language construct apparently).
