We cooked up a simple library that allows for serializing functions at the Seattle Clojure group: https://github.com/Seajure/serializable-fn It's able to serialize lexical scope along with the function, but there may be certain types of expressions that would cause trouble when they are closed over. It should be pretty easy to fix if you're interested in improving it a bit. This approach is a bit naive as it requires you to know in advance which functions you want to serialize and use the serializable fn macro, but depending on your needs it could get the job done. It has the advantage of being many many orders of magnitude simpler (20 LOC) than any other function serialization mechanism. -Phil -- You received this message because you are subscribed to the Google Groups "Clojure" group.
