What's the best way of concatenating results of macro calls together
which in turn get passed to another macro?

e.g. given a div_id(id, content) macro which produces an HTML div:  [1]
  <div id="$id">$content</div>

How do I best produce something along the limes of:
  <div id="header">
    <div id="left">foo</div>
    <div id="right">bar</div>
  </div>

Surely I don't actually need a temporary variable?
  [% headtext = div_id("left", foo) _ div_id("right", bar) %]
  [% div_id("header", headtext) %]

I can't get anything like:
  [% div_id("header", div_id("left", foo) _ div_id("right", bar) %]
to work ...

Thanks,

Tony

[1] And, how exactly should I call CGI.div when .div wants to act as a
divide?
