It must not. But add-to-list is by tradition older and more used function. And it will not require cl library such as `cl-pushnew'. I am verifying: (type-of company-backends) ⇒ cons (company-bbdb company-eclim company-semantic company-clang company-xcode company-cmake company-capf company-files (company-dabbrev-code company-gtags company-etags company-keywords) company-oddmuse company-dabbrev) This is the list, so you may use any method you wish to put elements in the list. -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.
