I think I see your point, but it feels weird to see this form, to me.

To your point, I can see the opening tag as ( and the closing as ), but then that would lead to something more like:

    (table
      (tr
        (td one
        (td two
        (td three
      (tr
        (td ...

Which really just highlights how odd it is to see the opening tags without the closing ones. Which probably goes a long way to explaining why I don't like it. :D

Probably more natural to have something like:

    (html 
      table
        tr
          td "one"
          td "two"
        tr
          td "...")

In this way, you could optionally have the closing tags of /td and such. Still looks very weird to me.
