It depends on what `pop' you're using. With the cl.el pop, you get this:
(setq lst '("a" "b" "c"))
=> ("a" "b" "c")
(pop (nthcdr 1 lst))
=> "b"
lst
=> ("a" "c")
With the Emacs Lisp `pop', you get this:
(setq lst '("a" "b" "c"))
=> ("a" "b" "c")
(pop (nthcdr 1 lst))
Debugger entered--Lisp error: (wrong-type-argument symbolp (nthcdr 1 lst))
