这是 Java 互操作性的必要解决方法.

It's a necessary workaround for Java interoperability.

当 Clojure 命名空间被 AOT(提前)编译成 Java .class 文件时，它的名称必须是有效的 Java 标识符.破折号在 Java 类名中无效，因此 Clojure 将它们转换为下划线.它还可以将 * 之类的字符转换为 _STAR_ 之类的词.

When a Clojure namespace is AOT (ahead-of-time) compiled into a Java .class file, it has to have a name that is a valid Java identifier. Dashes aren't valid in Java class names, so Clojure converts them to underscores. It also converts characters like * into words like _STAR_.
