The key is to understand that in Clojure, values and references are separate, and references can be mutated but in a particular, concurrency-aware way: http://clojure-doc.org/articles/language/concurrency_and_parallelism.html#identity/value-separation-("on-state-and-identity") -- MK -- You received this message because you are subscribed to the Google Groups "Clojure" group.
