SYNOPSIS

    my $c = Cache::Profile::Compare->new(
        caches => [
            Cache::Bounded->new({ interval => 256, size => 1024 }),
            Cache::Ref::LRU->new( size => 1024 ),
            Cache::Ref::CART->new( size => 1024 ),
        ],
    );

    # use normally
    $c->get("foo");
    $c->set("foo" => 42);

    # reports which cache had the best hit rate, and which provided the best
    # speedup
    $c->report;
