Relevant page here:
http://www.gnu.org/s/emacs/manual/html_node/elisp/Quoting.html
I was confused and always assumed that
'(a . b)
is simply short hand for
(cons 'a 'b)
Reading stackexchange, it seems at least some other people are under
this impression as well. This works a majority of the time, but when
it fails it's really surprising.
In fact, the manual already has an example of this pit-fall in the
nconc section:
http://www.gnu.org/software/emacs/elisp/html_node/Rearrangement.html
I think the quoting section should give an explicit warning with a
reference to the nconc example.
