In some situations, you need to know not only the value of the item to be removed from the cache, but also the key. The project I'm working on needs to get that key and do some work with it. I propose to add such functionality, like this:
template <class T, class K>
const K& LRUCacheKeyRet<T, K>::GetLRUKey()
{
	int tail = data[head].prev;
	return key[tail].key;
}
