Release 0.4.0 adds support for context map that is passed through requests.

Example:

(def request1 [user-id context cb]
  (cb user-id (assoc context :some-state "state")))

Now next requests context contains map with key :some-state

[slipset]

Would that be

(defn request1 [user-id context cb]
  (cb user-id (assoc context :some-state "state")))

[mhjort]

There was a mistake. It should be like this

(def request1 [user-id context cb]
  (cb true (assoc context :some-state "state")))

I improved documentation a bit to make this more clear. My plan is to write a full blown example next to make usage more clear overall.
