自 1.8.0 以来解构规范有变吗？

Question

1.8.0:

clj-rcon-test.core=> (defn- hi [as-codec & {:keys [offset] :or {:offset 0}}]
                #_=>   (println "hi"))
#'clj-rcon-test.core/hi

1.10.0:

clj-rcon-test.core=> (defn- hi [as-codec & {:keys [offset] :or {:offset 0}}]
                #_=>   (println "hi"))
Syntax error macroexpanding clojure.core/defn- at (form-init17556793069765460591.clj:1:1).

clj-rcon-test.core=>

为了了解背景，这是我在尝试解决问题：[链接](https://github.com/gpittarelli/clj-rcon/blob/master/src/clj_rcon/codecs.clj#L6)

Answer 1

这里的问题是 :or 期望的是一个符号到值的映射的映射，而不是关键字到值的映射。不确定这可能是规范中的疏忽，还是它根本不应该被支持。

谢谢，这样有效！

过去，这是无意中允许的，现在已经被加强了。重要的是，以前它默默地不起作用。
