Of course you can redef a Var via function. (defn foo [y] (def x y)) (foo 5) However, you cannot define arbitrary Vars. (defn bar [x y] (def x y)) (bar 'c 5) This does *not* define Var named c. So can't really make 'dynamic' calls to def at runtime. Just as Stuart writes. Sincerely Meikel -- You received this message because you are subscribed to the Google Groups "Clojure" group.
