I've got no clue, so I would just do the experiment. If it works out

Hi folks,
Would those more knowledgable about Clojure care to weigh in on
whether it be a good idea to create a custom class inheriting from
IDeref? I've been considering creating session proxy objects (to be
later replaced with protocols) that would respond to deref calls, e.g.
(def session
I don't know, but it seems like a bad smell that you can't find your

The build-in state management constructs only deal with data in

I can't comment on style, but I can say I successfully made a protocol
to implement SoftReferences:

(.get ref)))
(defn soft-reference
returns a soft reference to x. Access using deref
