Symbols need to be namespace resolved in order to be evaluated properly. This is something you need to be aware of, but it is not unpredictable or contrary to any documentation. And again, in this case, the evaluation of the plus symbol does not happen at macro expansion, it happens at run time. The behavior here is the same inside of and outside of a macro: user=> (def e '(5 + 2)) #'user/e user=> (eval `((nth '~e 1) (nth e 0) (nth e 2))) 2 user=> (eval `((nth (list ~@e) 1) (nth e 0) (nth e 2))) 7 > Where it mustn't evaluate a symbol (argument of macro), it does. This has already been shown in several responses, the argument is not being evaluated in macro expansion, it is being evaluated at runtime. Using macroexpand will help you to see what the expanded forms look like and what namespace symbols are resolved to. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
