I notice it happens on Clojure 1.5.0-master-SNAPSHOT also. Calling something like: (future-cancelled? f) *true* before getting @f makes sense, but since I'm a clojure newb I don't know what showing "f" (not @f) would show. Maybe it should show something like: #<core$future_call$reify__3499@7c9391d9: :cancelled> and only @f should throw. That would make some sense to me. And it would make me understand what you wanted. But it appears as if it's trying to also show @f or maybe only show @f instead of the ":cancelled" part, as it does when the future is "future-done?"
