"re-def" a non-dynamic var to a ^:dynamic var make a mistake
Hi,everyone! I'm a newbie here.When I'm reading Mark Volkmann's Tutorial,i make a mistake by binding a non-dynamic var 'x' to new value.Then I def 'x' with ^:dynamic again,but in this line (binding [x 9] (foo)), the function 'foo' ignore the binding.Why? Thanks for reply!!! uer=> (def x 0) #'user/x user=> (defn foo [] (println x)) #'user/foo user=> (foo) 0 nil user=> (def ^:dynamic x 1) #'user/x user=> (foo) 1 nil user=> (binding [x 9] (println x)) 9 nil user=> (binding [x 9] (foo)) 1 nil -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Thanks Meikel ! It works after I recompile foo. It seems like you are right. :) On Dec 8, 3:28 pm, "Meikel Brandmeyer (kotarak)" wrote: > Hi, > > just a guess: ^:dynmamic is a compile-time thing. foo was compiled without > it in place, so the compiler didn't consider it.
