I frequently use the following command (bound to `C-c l'), which suits
my needs better than the proposed command would or dabbrev-expand does:

(defun srb-select-line ()
  "Select line at point and copy to kill ring."
  (interactive)
  (copy-region-as-kill (line-beginning-position) (line-end-position)))

A common use case for me is copying somewhat complex shell commands I
keep stored in a file; they are stored as one liners to be easy to copy.
I don't want them to be immediately yanked into the file and for these
cases I don't need the feature of multiple copies via a prefix argument
(though in some documents I often do want multiple copies of a single
line, but usually at different parts of the document, so then just
yanking at the different locations is better than moving the copies).
