user=> (defn record-factory [recordname]
#_=> (let [recordclass ^Class (resolve (symbol recordname))
#_=> max-arg-count (apply max (map #(count
(.getParameterTypes ^java.lang.reflect.Constructor %))
#_=> (.getConstructors
recordclass)))
#_=> args (map #(symbol (str "x" %)) (range (- max-arg-count
2)))]
#_=> (eval `(fn [~@args] (new ~(symbol recordname) ~@args)))))
#'user/record-factory
user=> (ns foo)
nil
foo=> (defrecord Bar [x y])
foo.Bar
foo=> (ns user) ;;back to user ns (doesn't depend on foo)
nil
user=> ((record-factory "foo.Bar") 1 2)
#foo.Bar{:x 1, :y 2}

Yes it would...You're using reflection so no need to :use or
:require the namespaces any more.
Point your browser here if you're not following:

What gets those classes loaded/imported to begin with? I don't see
how the classes ever get built if nobody requires the file containing
the defrecords.
