Re: [Sbcl-help] New user - Various Questions, SETQ, adding lists...

Oh no, I left out an important part of the session, after the second
(defvar foo 'a)!

It should be as follows:

> CL-USER> (defvar foo 'a)
> FOO
> CL-USER> foo
> A
> CL-USER> (setq foo '(a b c))
> (A B C)
> CL-USER> foo
> (A B C)
> CL-USER> (setf (car foo) 10)
> 10
> CL-USER> foo
> (10 B C)
> CL-USER> (defvar foo 'a)
> FOO
> CL-USER> foo
> (10 B C)
> CL-USER> (setq (car foo) 100)
