Aeson/Haskell doesn't require decoding json into user-defined data types. It supports the scenario of turning the data into a plain Map (clojure style) as well. The plain Map style is simply a less preferred paradigm in haskell, but its very easy to support this. Getting a map out from your json is a one liner.
