   A quick solution for getting just the elements would be to wrap the
(siblings) call with something like:

        (select-by-class (siblings) 'element)

   I don't recall what the support for (select-by-class) is in various
versions of Jade/OpenJade, so here's an off-the-top-of-my-head,
completely-untested implementation:

        (define (select-by-class nl sym)
          (node-list-filter (lambda (snl) (member sym
                                (list (node-property 'classnm snl)
                                  (node-property 'classnm snl rcs?: #t))))
                            nl))

   If you're missing node-list-filter, there's an implementation in
the standard (or the procedure library, I'm sure).
