Now I tried something even more radical, a completely different approach
to the problem, just to see what happens.

(defun Textile-list-context (textile-list-tag)
  "Return list of HTML tags corresponding to list context (ol, ul)."
  (let ((my-list (delete " " (delete "" (split-string textile-list-tag "")))))
    (mapcar (lambda (x)
               ((string= x "#")
               ((string= x "*")
                nil))) my-list)))

_It still returns a circular list._

And it still does the right thing, when I call it from a scratch buffer.

Clearly there is something deep about lists that I don't get right now.
