Have found completing-read-multiple.  But need some help understanding 
the exact format.  I want to set company-backends.  How would one pass
the multiple arguments in elisp code?  

Should I use

   (defun cbackends (&rest actm-seqr)

or keep it as is?

(defun cbackends (actm-seqr)

  (interactive
    (let* ( (cseq '("company-dabbrev"
                    "company-dabbrev-code"
                    "company-keywords"
                    "company-capf"
                    "company-yasnippet"
                    "company-files"))

            (backends-seltr
                (completing-read-multiple
                  "Backends Multi-Seltr (comma-separated): "
                  cseq nil t)))

      (list (mapcar #'intern backends-seltr))))

    (setq company-backends actm-seqr))
