Can you elaborate how you re-define what clojure is? Then assuming we make no claim on ease of updating or strict adherence to what Clojure is defined to do, in other words we are making an evolution of ClojureScript, what would the PyPy implementation look like? How would things be simpler, and more complicated? What's the minimal set of functionality that needs to be implemented in RPython so that we can begin to define clojure.core. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
