I thought of protocols initially here too, but protocols just define functions, so where would the data live that you want as metadata?
A closure over the data? This implies extending the protocol on a per-instance basis, which afaik doesn't exist (cljs design work aside http://dev.clojure.org/display/design/specify+i.e.+reify+for+instances). Some global map? We can't key on arbitrary java objects since the hashcode can change. Is there a key that will work? A var? We can already do that. Maybe there's someplace I'm missing where you could store this data and look it up later via a protocol implementation? -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
