Re: Call macro with new root

It's not possible to do as far as I see. Especially as it should be
lexically scoped (in most applications at least). The best you can do
is something like:

  <#macro Product>
    <#local c = latestProduct> <#-- c for context -->
    ${c.name} (${c.url})
  </#macro>

Then at least it's obvious what's going on...
