-## Todo
-- lmdb
-  - get maybe !? weil nicht vorhanden und fehler unterschiedlich behandelt werden sollten
-  - Listen in eigene dbi weil dbi's sonst nicht sinnvoll iteriert werden können
-- Anstatt Posts in posts dbi, vielleicht ownen die PostList's der User die Posts?
-  - aber dann können wir wieder nicht iterieren...
-  - anhand der Key Länge unterscheiden zw. SetList und Item und Post?
-  - alternativ eigene dbi's für SetList, item und dann posts, users usw.
-- Change respond (respondoptions -> request, fmt+args)
-- Rewrite get_value
