Subject: Add-to-list or setq append...
Date: Wed, 04 Aug 2010 00:37:03 +0200 [thread overview]
Message-ID: <m1sk2vz5kg.fsf@gmail.com> (raw)
Just a curiosity, I was wondering why in so many README and doc they
suggest to add elements to lists with something like:
--8<---------------cut here---------------start------------->8---
(setq list (append list element))
--8<---------------cut here---------------end--------------->8---
instead of doing simply
--8<---------------cut here---------------start------------->8---
(add-to-list list-va element)
--8<---------------cut here---------------end--------------->8---
Is there any good reason or is just historical heritage?
I think add-to-list is even more smart adding only if not there already,
then what's the point in using that ugly form?
