A long time ago I posted some macros to do double-dispatch with protocols and records. The link was http://paste.lisp.org/+2023 but it no longer works.
The basic idea is you dispatch on the first argument to an intermediate type that then dispatches on the second argument. It's complicated, but essentially mechanical. Clojure multimethods have built-in multi-argument dispatch. -S -- You received this message because you are subscribed to the Google Groups "Clojure" group.
