如何让这三个片段有效?
(defn bar [a b c] (println a b c))
> (bar :a :b :c)
:a :b :c
(defn foo [a & args] (bar a args)) ;; some magic is needed here.
> (foo :a :b :c)
MoralException: You're a bad person for trying this.
我已经全神贯注地看到了如何做到这一点。我尝试过很多像(apply bar [a args])
这样的东西,但这是一个ArityException(这很有意义)。我该怎么办?

您不需要在向量中将参数包装到apply
。
(apply bar a args)
干预参数前置于args
。
