This was John Rankin's original conception of trails -- I didn't implement
it at the time because of the issue of automatically adding the trail into
the page.  But we still have the option of doing this.

I propose <<||>>, or perhaps even <<|{$Trail}|>>.  

But this still feels like a halfway measure to me -- if we're going this far, 
there ought to be some way to have the trail automatically appear 
even w/o the markup.  But so far the mechanisms I can imagine for doing this
aren't very pleasing.
