对SBCL中的``ql:quickload``和可执行脚本感到困惑

Question

我一直在尝试在我的可执行脚本中使用Quicklisp包.一个(平凡的)工作示例是:

#!/usr/bin/sbcl --script

(eval-when (:compile-toplevel :load-toplevel :execute)
  (ql:quickload "lisp-unit")) ;as explained by another question

(defpackage :test
  (:use :cl :lisp-unit))

(format t "This is a test.")

在chmod使用此代码(调用test.lisp)的文件后,我尝试执行它.但是,我收到以下错误消息:

Unhandled SB-C::INPUT-ERROR-IN-LOAD in thread #<SB-THREAD:THREAD
                                            "main thread" RUNNING

我不确定这里发生了什么 - 如果我尝试从顶层做类似的事情(即,启动SBCL,加载lisp-unit使用ql:quickload等),我不会得到这样的东西.

在SBCL中,--script不加载您的init文件.如果要使用Quicklisp,则必须安排加载它.这通常意味着(load "~/quicklisp/setup.lisp")在使用与Quicklisp相关的任何东西之前.

我不认为SBCL和Quicklisp非常适合编写脚本任务.当我编写脚本时,我通常不会期望它们像在互联网上那样从中获取内容ql:quickload.Quicklisp也非常冗长.SBCL的FASL加载非常缓慢.总而言之,它并不能带来非常好的脚本体验.

我非常希望将我需要使用的所有内容加载到Common Lisp会话中,然后调用函数来完成任务.当我不能使用它时(比如从cron或Makefile运行东西),我经常使用buildapp来制作可执行文件.
