* PHP-FIG has been developing a draft standard for caching,
* PSR-6. The standard has not been ratified yet. When
* making changes to this interface, please take care to
* avoid *conflicst* with PSR-6's CacheItemPoolInterface. At
* time of writing, they do not conflict. Avoiding conflicts
* will enable more transition paths where Civi
* simultaneously supports both interfaces in the same
* implementation.
*
* For example, the current interface defines:
*
* function get($key) => mixed $value
*
* and PSR-6 defines:
*
* function getItem($key) => ItemInterface $item
*
* These are different styles (e.g. "weak item" vs "strong item"),
* but the two methods do not *conflict*. They can coexist,
* and you can trivially write adapters between the two.
*
* @see https://github.com/php-fig/fig-standards/blob/master/proposed/cache.md
