Tie::Cache::LRU::Array - Tie::Cache::LRU implemented using arrays
use Tie::Cache::LRU::Array; tie %cache, 'Tie::Cache::LRU::Array', 500; ...the rest is as Tie::Cache::LRU...
This is an alternative implementation of Tie::Cache::LRU using Perl arrays and built-in array operations instead of a linked list. The theory is that even though the algorithm employed is more expensive, it will still be faster for small cache sizes (where small <= ??) because the work is done inside perl (ie. higer big O, lower constant). If nothing else, it should use less memory.
