;; Without quote - passes the VALUE of myplist
(lana-du-fpln myplist)  ; passes the actual list/object

;; With quote - passes the SYMBOL 'myplist itself
(lana-du-fpln 'myplist) ; passes the symbol, not its value

So if you wish to see the name of symbol you must use the second
solution and then derive the value from it.

(setq myplist '(:a 1 :b 2))

(defun show-info (sym)
  (message "Symbol name: %s" (symbol-name sym))
  (message "Symbol value: %S" (symbol-value sym)))

(show-info 'myplist) ⇒ "Symbol value: (:a 1 :b 2)"

Symbol name: myplist
Symbol value: (:a 1 :b 2)
