Cache::Ref::CAR - CLOCK with Adaptive Replacement
my $c = Cache::Ref::CAR->new(

This algorithm is an implementation of
See also Cache::Ref::CART which is probably more appropriate for random access
CAR balances between an MFU like policy and an MRU like policy, automatically
tuning itself as the workload varies.
- 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.
