Hmm, highly apropos discussion since Rich's talk on simplicity posted today. The reader does one thing: read Clojure data. Sometimes you need something else: read data written in another format. You might accomplish that by (1) making the reader able to do two things, adding a flag to deal with a specific format, or (2) by using a different reader for that job. (2) is hands-down the right answer. Stu -- You received this message because you are subscribed to the Google Groups "Clojure" group.
