There's also this issue raised in the bug tracker (by Chas Emerick I presume ?) which is about adding a nice java facade for this kind of interop (and thus also ensuring some independance towards clojure internals). What about bringing it back to the table for inclusion in 1.3 ? -- You received this message because you are subscribed to the Google Groups "Clojure" group.
