Be sure to have multiple get methods.  Memcache#get() returns just the 
key in a scalar form.  Memcache#get_a() returns a parallel array to 
what you put in as arguments with nil filled in at the appropriate 
array index.  Memcache#get_h() returns a hash of key->value pairs.  
Since arrays and hashes are the same in PHP, you probably want to have 
a get() method, and a get_array() method.  Having to deal with arrays 
if you only want one value is a huge PITA.  -sc
