First of all, I think this is a wonderful addition to the language. I've tried what is in the "new" branch on a small but real example, and I am quite happy with it: So thanks! Could you go into more detail about how protocols and datatypes are actually implemented, and the performance improvements you've recently made? (probably I'm not the only one interested :-) What is generated when I define a protocol, datatype and extend the type to the protocol? As I understand the performance of calling a protocol function matches the performance of calling an interface method in Java. How is it possible to achieve this in combination with the dynamic extensibility of extend? /Karl -- You received this message because you are subscribed to the Google Groups "Clojure" group.
