Using the trait must result in that items gets saved.
We could use `saveDeferred` instead, it might be a performance improvement but you also may have side-effects. Say you are using two cache pool objects for the same storage.
Example use of the trait:
```php
use Psr\Cache\CacheItemInterface;
use Psr\Cache\CacheItemPoolInterface;
use Symfony\Contracts\Cache\CacheInterface;
use Symfony\Contracts\Cache\GetForCacheItemPoolTrait;
class AcmeCache implements CacheInterface
{
use GetForCacheItemPoolTrait;
private $cache;
public function __construct(CacheItemPoolInterface $cache)
{
$this->cache = $cache;
}
public function getItem(string $key): CacheItemInterface
{
return $this->cache->getItem($key);
}
public function save(CacheItemInterface $item): bool
{
return $this->cache->save($item);
}
}
```
