That's caused by the collision between new and existing keys. Renaming
1 to 2 blows [2 :b]: {2 :a, 3 :c}; then renaming 2 to 3 blows [3 :c],
leaving {3 :a}; and the last just renames 3 to 4: {4 :a}.

Given the current implementation I really don't see how this could work.

Paul,
I'm using ring, hiccup, compojure, and clutch (for my database
connectivity via CouchDB). I'm avoiding Sandbar, cause I can't figure
too much of it out anyways) at this point, at least.
I think the only thing I'm using compojure for is [GET POST ANY

The "magic" is in wrap-session, which adds the session middleware to your stack.
At that point, your ring handler will see that it's request map has a
new key (:session) which is a map containing all your session
variables.
You can assoc anything into that map and it will be stored in the session

The real problem is that first case was never actually specifying a return
type - it is a type hint on the var that happened to store an fn. The fn
itself can only return Object (<=1.2.0).

Shree,
I would suggest that you try to use only Ring first. Once you get how
it works, take a look at Sandbar and see if that may work better for
you in specific situations.
The session code in Sandbar is stable. It will not change much in the
next release. In fact it may become its own project b

That didn't seem to make any difference. I believe the example I got

I've released a new version of lein-daemon. daemon is like 'lein run',
only it runs the process in the background rather than blocking.
0.3 and up is a complete re-write, that no longer depends on apache
commons daemon. The new version has no dependencies on any external
programs.

Factual has been using Clojure for over a year now in narrowly defined
