Lately I've leaned towards going full monty the first time out: stop guessing and optimize everything past the entry point to the critical section. It sounds like more work up front, but in the end it's the "smart" approach that results in more total effort. > Fortunately, dropping down to Java is relatively painless.

I think that plays a big part in why ClojureScript can be more transparent. -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
