But : * in Clojure 1.2 : these binding do not automatically flow from thread to thread, so they do not work "in the general case" (though arguably this general case may not be the usual case) * in Clojure 1.3 : the bindings will now flow from thread to thread when using clojure primitives (agents, futures, pmap, etc.), *but* the default for vars will change from dynamic rebindable to not dynamic rebindable (dynamic rebindability will have to be explicit)
