And it wouldn't have to be that much effort, especially if the OP's suggestion
(foreach) is an indication of the complexity. In fact, the example that's listed
on the OP's link is a dead-simple mapping to Ruby:

Smarty:
{foreach name=outer item=contact from=$contacts}
  {foreach key=key item=item from=$contact}
    {$key}: {$item}<br>
  {/foreach}
{/foreach}

Ruby:
contacts.each() do | contact |
  contact.each_pair() do | key, item |
    puts "#{ key }: #{ item }<br>"
  end
end

In fact, if this is as tough as it gets, writing a Ruby interpreter for Smarty's
syntax should take no time at all, even for a beginner in the language (like me).
