我正在使用 Doug Hoyte 和 The Phoeron 的 let-over-lambda 的示例来同时建立我对 common-lisp 包、quicklisp 和 asdf 以及在 common lisp 中进行大规模编程的生产级专业实践的理解。
我能够以如下所示的方式使用该包，但还没有弄清楚如何使用类似的部分引导猜测来运行它的测试。详情如下。
我在这里找到了代码：https ://github.com/thephoeron/let-over-lambda 。我正在使用“消防软管”和“渐进式教育猜测”的方法尽可能快地将其塞进我的脑海中，并以此为指导。当然，与更结构化的方法相比，这种方法会给我留下更多模糊的知识点，但它可能会让我更快地到达山顶（请随意驳斥我的这个想法）。
以我目前的初步了解，我可以在自己的代码中使用该包。例如，我可以写
(load "~/quickload/setup.lisp")
(ql:quickload "let-over-lambda")
(let-overlambda:flatten '((a . b) c (d e)))
并得到
(A B C D E)
lol通过阅读“package.lisp”中的内容，我可以注意到该包定义了一个昵称defpackage，即（缩写）：
(defpackage #:let-over-lambda
(:nicknames #:lol)
(:use #:cl #:cl-user #:cl-ppcre)
我可以使用昵称：
(lol:flatten '((a . b) c (d e)))
=> (A B C D E)
甚至导入它的导出，摆脱任何限定符号的需要：
(use:package :lol)
(flatten '((a . b) c (d e)))
=> (A B C D E)
现在，我注意到 repo 包含一个诱人的测试包和目录“t”：
-rw-r--r-- 1 921 Dec 5 05:27 let-over-lambda-test.asd
-rw-r--r-- 1 941 Dec 5 05:27 let-over-lambda.asd
-rw-r--r-- 1 17421 Dec 5 05:27 let-over-lambda.lisp
-rw-r--r-- 1 1771 Dec 5 05:27 package.lisp
drwxr-xr-x 3 102 Dec 5 05:27 t
不过，我无法弄清楚如何运行测试，这是我的问题：我该怎么做？以下是我在 sbcl 1.3.1 中尝试过的一些事情，但未成功：
* (ql:quickload "let-over-lambda-test")
debugger invoked on a QUICKLISP-CLIENT:SYSTEM-NOT-FOUND in thread
#<THREAD "main thread" RUNNING {1002ACC943}>:
System "let-over-lambda-test" not found
Type HELP for debugger help, or (SB-EXT:EXIT) to exit from SBCL.
restarts (invokable by number or by possibly-abbreviated name):
0: [CONTINUE] Try again
1: [ABORT ] Give up on "let-over-lambda-test"
2: Exit debugger, returning to top level.
((LABELS QUICKLISP-CLIENT::RECURSE :IN QUICKLISP-CLIENT::COMPUTE-LOAD-STRATEGY) "let-over-lambda-test")
0]
和这个
* (load "./t/let-over-lambda.lisp")

编辑：快速加载“证明”，如下所示，将一堆更酷的东西加载到我的环境中，但仍然让我不知道如何运行测试。我原以为“证明”会自动快速加载为defsystem“let-over-lambda-test”中的依赖项，所以这是一个小惊喜：
* (ql:quickload "prove")

我将不胜感激任何指导。
