- * 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.
