Description:
------------
Probably a little much asking for this, but I think it'll 
helps in 
consolidating multiple calls for differing types of value 
from 
memcached into one getMulti/getDelayed style call..


$keys = array(
'Key1' => function($value) { ... },
'Key2' => function($value) { ... },
);

$memCached->get...($keys);

Instead of having to 

$r = $this->cache->getMulti(array_keys($keys));
if (is_array($r))
   foreach($r as $key => $value)
     $keys[$key]($value);
