Subject: Why doesn't nconc change my variable?
Date: Sun, 05 Oct 2014 03:36:49 +0200 [thread overview]
Message-ID: <87y4svl2ku.fsf@wmi.amu.edu.pl> (raw)
Hi list,
I don't get it.
(setq my-list ())
(nconc my-list '("wtf"))
and my-list is still nil.
If, OTOH, I do
(setq my-list ())
(setq my-list (nconc my-list '("wtf")))
my-list is ("wtf").
Why is that so? I though nconc is supposed to change all its arguments
but the last one. Is the latter construct a correct way of adding an
element at the end of the list?
Best,
--
