Memcached::set() and Memcached::get() both look for a string as the first
(ie key) parameter.

public bool Memcached::set ( string $key , mixed $value [, int
$expiration ] )

public mixed Memcached::get ( string $key [, callback $cache_cb [, float &
$cas_token ]] )

This suggests to me that keys must be strings, and so an array of keys
must be an array of string values. Hence the numeric value 1234 may not
be a valid key value even if it's in an array.
