What do you mean by "unwrap a list"?
If you mean something where:
(foo (unwrap 1 2 3)) == (foo 1 2 3)
Then I'm afraid this can't be done. A macro returns a single data structure.

I am trying to write a macro to unwrap a list:
here's my naive attempt
(defmacro unwrap [s]
(-> s pr-str (clojure.string/replace #"[\(\)]" "") read-string))
(unwrap (1 2 3) ) should give 1 2 3
any ideas how this can be done?
thanks,
Sonny
