The function cycle-themes have cycle-themes-theme-list as a quoted list, e.g., (setq cycle-themes-theme-list '(tsdh-light wheatgrass whiteboard womba)).
At the same time, (custom-available-themes) will return all available themes. How do I apply the quote to this expanded list?
#+begin_src emacs-lisp
(use-package cycle-themes
:ensure t
:init (setq cycle-themes-theme-list
(quote-after-expand (custom-available-themes))))
#+end_src
