It's a good habit to initialize your variables directly when you declare
them (in C-style languages as well, BTW):

 (defun copy-line ()
   (interactive)
   (save-excursion
     (beginning-of-line)
     (let ((beg (point)))
       (end-of-line)
       (copy-region-as-kill beg (point)))))

In elisp it's also marginally more efficient.
