No, but you can say:

(dolist (group gnus-newsrc-alist)
  (when (string-match "^nnml:\\(.*\\)$" (setq group (car group)))
    (insert (format "(\"^%s$\" (to-group . \"%s\"))\n"
		    group (match-string 1 group)))))

:-)                    

Having a more general substring match thing going on in that variable
would be possible, but I don't quite see how to express that:

For example:
   (("mail\\..*"  (gnus-show-threads nil)
		  (gnus-use-scoring nil)
		  (gnus-summary-line-format
			"%U%R%z%I%(%[%d:%ub%-23,23f%]%) %s\n")
		  (gcc-self . t)
		  (display . all))
     ("mail\\.me" (gnus-use-scoring  t))
     ("list\\..*" (total-expire . t)
		  (broken-reply-to . t)))

There's many params that contains strings...  Well, I guess "\\1"
(etc) in them all could be replaced by the matching sub string.  Would
that be useful?
