Yes, simple, but useful.

Well, how about this (adapted from the sidebar example): sorting by crumb
value, inverse order.

    .. raw:: html
   =20
        {+coloring}
       =20
	cmp_page =3D lambda page1, page2 : 2*(page1['crumb'] < page2['crumb'] ) =
- 1

        for page in sidebar(indextree, cmp=3Dcmp_page):
            val =3D page['crumb']
            link =3D page['target']
            if page['title']:
                print '<br /><strong><a href=3D"%s">%s</a></strong>' \
                % (link, val)=20
            else:
                print '<br /><a href=3D"%s">%s</a>' % (link, val)
       =20
        {-coloring}

But this allows for much more powerful uses (like having a "date"
uservalue, and sorting by date).
