Should I use a function or a macro to validate arguments in Clojure?

Question

I have a group of numeric functions in Clojure that I want to validate the arguments for. There are numerous types of arguments expected by the functions, such as positive i

Answer 1

A case where you need a macro would be if you wanted to modify the language to automatically add the tests to any function defined within a block, like this:

(with-function-validators [test1 test2 test4]  
    (defn fun1 [arg1 arg2] 
        (do-stuff))
    (defn fun2 [arg1 arg2] 
        (do-stuff))
    (defn fun3 [arg1 arg2] 
        (do-stuff)))
