Is this because functions are handled differently? --8<---------------cut here---------------start------------->8--- user> (def foo "hello") #'user/foo user> (def a foo) ;; a has the current value of foo #'user/a user> (def b #'foo) ;; b's value is the Var foo #'user/b user> (def foo "goodbye") #'user/foo user> a "hello" user> b #'user/foo user> @b "goodbye" --8<---------------cut here---------------end--------------->8--- Please note that you have to dereference b explicitly to get the value currently bound to foo. That's because b's value is again a Var. It seems that Clojure dereferences Var's automatically, possibly multiple times, in case of function calls. So in Stuard's example, both (b) and (@b) call the function currently bound to foo. Bye, Tassilo -- You received this message because you are subscribed to the Google Groups "Clojure" group.
