No, not really. You could also make the symbols for the API class an
additional arg to the macro, like:
(defmacro with-api-connection [conn-sym api arg1 arg2 & body]
`(let [~conn-sym (. ~api getConnection ~arg1 ~arg2)]
(try
~...@body
(finally (. ~api closeConnection ~conn-sym)))))
but then the macre application would be longer.
(with-api-connection [c API1 "localhost" 12345]
(with-api-connection [c2 API2 "141.55.22.1" 13321]
(do-stuff-with c c2))
(do-stuff-with c))
