Usage would be (partial* fun _data 1 :test _index) returning something like (fn [_data _index] (fun _data 1 :test _index)) So you get back a 2 arg function with some parameters already filled in by either constant data or closed over bindings. The macro would need to use some sort of convention to recognize which symbols are meant to be used in the new function arglist, I've used _ as the prefix. I don't have time right now to actually write the macro :) Brad --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
