Need to be able to do:

• delete key
• set ttl (either separately or as part of a set - both would be nice)

Desirable

• get ttl (if possible - may be too much to get memcached to do it)
• increment / decrement

Done.

$cache->set('key', 'value', ttl);
$cache->set('key', 'value', ttl, sub { });

my $ttl = $cache->ttl('key');
$cache->ttl('key', sub { my $ttl = shift });

The ttl method returns the remaining TTL, not the original TTL.

It's emulated on Memcached backends - first need to set get_ttl_support, e.g.

$cache->backend->get_ttl_support(1);
