How to pass in object definition body to a function

Question

My goal is to DRY up the repetitive parts of the definition of objects passed to a generic function in the following block of code:

renderTpl(response, "person.html", new Transformer {
  $(".person :first-child").contents = name
  $(".person :last-child").contents = age
})

I would like to DRY out the new Transformer part and be able to pass the block in the 2nd argument list of renderTpl instead:

renderTpl(response, "person.html") {
  $(".person :first-child").contents = name
  $(".person :last-child").contents = age
}

is it possible to achieve this without resorting to macros? I would post my attempts so far but to be honest I couldn't come up with anything right now.

Background: I'm using Scalate's awesome Scuery with servlets, combined with Lift's net.liftweb.util.Html5 and org.ccil.cowan.tagsoup for HTML5 parsing and rendering; the current renderTpl and loadTpl implementation can be seen here.
