You could use the :default option of the edn-reader e.g
(import 'clojure.lang.Reflector)
(defn- read-extended-ctor [class map]
(Reflector/invokeStaticMethod (Class/forName (name class)) "create"
(object-array [map])))
(defrecord x [a b])
(edn/read-string {:default read-extended-ctor} "#user.x{:b 2}")
;=> #user.x{:a nil :b 2}
