It seems that when MemcachedAdapter is used with TagAwareAdapter, it fails to fetch items, even though I thoroughly tested fetching items with the exact same keys under the same namespace.Turns out the issue lies in `const TAGS_PREFIX = "\0tags\0";` for unknown to me reasons. Hardcoding that to '__tags__' in my project did the trick and I've been using it for a couple of days now and it seems fine.The reason I had to completely copy/paste this file in my local project is self:: instead of static:: usage. I am not sure whether that is a mistake or is done on purpose, but in order to have this work for me I need to be able to override that constant. Going with static:: seems like a good solution to me, then I can set whatever prefix I need for the tags.
