I am learning common lisp.
It's not explained anywhere but I tried:
(eq '(a b c) '(a b c))
which evaluates to NIL.
Why returning Nil from lisp's perspective? I am interested to know how it evaluates to Nil in this case.
Thank you.

3*"It's not explained anywhere"* :-D. Please have look at https://stackoverflow.com/questions/547436/whats-the-difference-between-eq-eql-equal-and-equalp-in-common-lisp – coredump Jul 15 '16 at 18:54

Generally it is undefined if that expression returns NIL or T in a Common Lisp program. So don't get too excited that in your case you got NIL as a result. – Rainer Joswig Jul 15 '16 at 19:07

your link said (eq '(a . b) '(a . b)) might be true or false. why? – binarycrayon Jul 15 '16 at 19:08
