You can't do that without using atoms or something, because you're assigning to conn1 and conn2 twice. That's not legal in Clojure because what "let" gives you aren't variables, but local constants. One solution would be to add a new construct to the language: (try-let [bindings] (body) (catch...) (finally...)) where any exception during evaluation of the [bindings] would be caught just as if it happened inside the body, and of course the bound variables would be visible to both the catch blocks and the finally block. It could be implemented as a macro that duplicated the catch/finally blocks within and outside a let... -- Mark J.
