Please ignore me if this makes no sense (I've never used/needed a 
templating engine in Lua), but wouldn't the following "if" condition 
suffice for hash tables that are empty?

<elem l:for="i,v in ipairs(table)" l:strip="">
	<b>${i}.</b> <span>${v}</span>
</elem>
<elem l:if="next(table)==nil">
	It was just empty, too bad :(
</elem>
