Ah, is your background OOP? You'll find the functional world is pretty different. No "variables" in the traditional sense, no uncontrolled mutation, no "loops" in the traditional sense, no state in the OOP sense. def and defn only create top-level definitions - bindings of values to symbols - and intern is really an implementation detail that you want to keep away from. As you can see from my example, you can create a sequence of agents easily enough as a data structure, and then you can perform operations on that data structure. Agents provide controlled mutation in that they start out with an initial value and you send them a series of function invocations and they take on new values as each function invocation is applied asynchronously. I wonder what you might be trying to achieve? Or perhaps this is just initial experimentation? One thing you'll find about Clojure is how rarely you need mutation. At World Singles we have about 18,000 lines of Clojure with just two agents (used to provide measured asynchronous DB updates for a couple of very specific situations) and 27 atoms, which are nearly all just caches - only half a dozen of those are really "mutable state" (and we're consolidating that).
