NAME
       Cache::Ref::CART - CAR with temporal filtering

SYNOPSIS
	   my $c = Cache::Ref::CART->new(
	       size => $n,
	   );

DESCRIPTION
       This algorithm is an extension to Cache::Ref::CAR that has temporal filtering on the upgrading from MRU to MFU pool.

       This means that two subsequent accesses to the same key do not automatically make it viable for long term caching, to get upgraded to MFU
       status a key must be expired but known in the history.

       This is probably the most general purpose caching algorithm.

ATTRIBUTES
       size
	   The size of the live entries.

	   Note that the cache also remembers this many expired keys, and keeps some metadata about those keys, so for memory usage the overhead
	   is probably around double what Cache::Ref::LRU requires.
