Clojure:laziness + core.logic:无限循环

[英]Clojure: laziness + core.logic: infinite loop

Context 上下文

The following code infinite loops: 以下代码无限循环:

(defn ex13 []
  (take 5
        (run* [x]
       (listo (lcons `a (lcons `b (lcons `c x)))))))

Question: 题:

Is this supposed to be the right behavior? 这应该是正确的行为吗? (infinite looping?) On the other hand, code like: (无限循环?)另一方面,代码如:

(take 5 (range))

takes 5 elements and prints them out. 需要5个元素并打印出来。

This may be a bug, however that's not the right way to do it as the results of run* are not truly lazy anyhow. 这可能是一个错误,但是这不是正确的方法,因为run *的结果无论如何都不是真正的懒惰。

(run 5 [x]
   (listo (lcons `a (lcons `b (lcons `c x)))))
