Expand a vector into the arguments of a function

问题

Is there a way to expand a vector of values into the arguments of a function? e.g. something like this:

(defn addnums [a b]
  (apply + (flatten [a b])))

(def args [[1 2 3] [1 2 3]])

(addnums *args)

回答1:

You can just use apply again:

(apply addnums args)
