Clojure 打印不带括号的列表？

Question

是否有内置函数来打印没有顶级括号的列表项，或者是否有更好的编写方法

(defn println-list
  "Prints a list without top-level parentheses, with a newline at the end"
  [alist]
  (doseq [item alist]
    (print (str item " ")))
  (print "\n"))

得到输出

user=> (println-list '(1 2 3 4))
1 2 3 4 
nil

Answer 1

像这样的东西？

(apply println '(1 2 3 4 5))
1 2 3 4 5
nil

来自 Clojure docs for apply :

Usage: (apply f args)
       (apply f x args)
       (apply f x y args)
       (apply f x y z args)
       (apply f a b c d & args)
Applies fn f to the argument list formed by prepending intervening
arguments to args.
