问题描述

＃^ 是什么意思在Clojure？我的 The Joy of Clojure 的副本在任何地方都没有提及这个操作符（它不在索引中，也不在我看过的文本的任何地方）。我不能真正地搜索它与谷歌，因为操作符是由搜索框忽略的特殊字符。

What does #^ mean in Clojure? My copy of The Joy of Clojure doesn't mention this operator anywhere (it's not in the index or anywhere in the text that I've looked). I can't really search for it with Google, because the operator is made up of special characters that the search box ignores.
