My goal was to push as much of the logic into the `CacheManager` as possible, so that cache users would only have two functionalities: get the data (this could even be hidden by using a `property`-like descriptor) and invalidate the cache. There should be no need for cache users to "remember to first check if the cache is valid, then ...": this logic is common to all cache users, and can be integrated into the cache manager.''
