You can reuse the existing 'repeat N' clause instead of 'using (limit N)'.

(cl-loop for x being the matches of "^(defun \\(\\S +\\)" using (group 1)
         repeat 10
         collect x)

Regarding Drew's concerns about extending cl-loop with more non-Common
Lisp things, I just don't see that as a problem. I suppose it would be
nice to have a more easily extensible looping macro, like iterate [1].
That would be quite a bit of work though.
