Rebol中虚拟运行环境的自动修改功能
我想在函数执行完毕后自动修改它（上下文是在虚拟运行时环境中远程执行，该环境共享模拟函数堆栈的代码块（因为这个堆栈是共享的，我想每次为下一个命令重置所有内容）调用）请参阅 http://askblogautomation.com/developers-guide/），例如（完整上下文请参阅http://askblogautomation.com/install-wordpress/）：
install-wordpress
set 'install-wordpress func[][do read http://askblogautomation.com/install-wordpress/]
我想通用化上面的行与
execute 'install-wordpress
执行位置如下
execute: func[lit-word-command [lit-word!]][
do get lit-word-command
block-command: []
append block-command [do read]
append block-command to-url rejoin [http://askblogautomation.com/ lit-word-command]
set lit-word-command func[] block-command
]
但是当我尝试它时，它给出了错误：
** 脚本错误：执行预期的 lit-word-command 参数类型： 亮词
如何解决这个问题？
I want to auto-modify a function once it has executed itself (context is remote execution in a virtual runtime environment that shares a code-block which simulate stack of functions (because this stack is shared I want to reset everything each time for next command call) see http://askblogautomation.com/developers-guide/) like this for example ( for full context see http://askblogautomation.com/install-wordpress/):
install-wordpress
set 'install-wordpress func[][do read http://askblogautomation.com/install-wordpress/]
I want to genericize the above lines with
execute 'install-wordpress
Where execute is as below
execute: func[lit-word-command [lit-word!]][
do get lit-word-command
block-command: []
append block-command [do read]
append block-command to-url rejoin [http://askblogautomation.com/ lit-word-command]
set lit-word-command func[] block-command
]
But when I tried it, it gives error:
** Script Error: execute expected lit-word-command argument of type:
lit-word
How to fix this ?

要么更改调用行：
要么更改函数规范：
但不能两者都更改！
Either change the invoking line:
Or change the function spec:
But not both!
