Is print-dup a multi-method or a protocol and your set of Java objects closed? If so, you can extend print-dup to the Java objects to output #=(JavaClass. constructor args) or whatnot; if the set of Java objects is open-ended you may have to resort to #=(.readObject (ObjectInputStream. (ByteArrayInputStream. (binhex/decode "4JK09bX38dQ1jl...")))). :) (Implementation of binhex/decode, and of the encoding half of all of this, is left as an exercise for the reader.) -- You received this message because you are subscribed to the Google Groups "Clojure" group.
