How would you recommend flattening the structure to allow for embedded X
within X (where X is a table, UL, OL, etc)?  I can think of translating
this:

$template->param(
      sub => [
            {
                  title => 'foo',
                  url => 'foo.html',
                  sub => [
                        {
                              title => 'foo-1',
                              url => 'foo-1.html',
                        },
                  ]
            }
      ]
);

to something like this....

$template->param(
      stuff => [
            {
                  openlevel => 1,
            },
            {
                  title => 'foo',
                  url => 'foo.html',
            },
            {
                  openlevel => 1,
            },
            {
                  title => 'foo-1',
                  url => 'foo-1.html',
            },
            {
                  closelevel => 1,
            },
            {
                  closelevel => 1,
            }
      ]
);

Which could possibly be collapsed to ...

$template->param(
      stuff => [
            {
                  openlevel => 1,
                  title => 'foo',
                  url => 'foo.html',
            },
            {
                  openlevel => 1,
                  title => 'foo-1',
                  url => 'foo-1.html',
                  closelevel => 1,
            },
            {
                  closelevel => 1,
            }
      ]
);

Is that what you were thinking of?  I guess that this could then work in a
single template.  I would probably do something more like this:

$template->param(stuff => flattenstructure($structure));

to try to automate / reuse it, but I think that may work.

Thanks for the alternate perspective.
