now I can't remember whether the lastest version of Smarty
allows foreach Iterator overloading on objects yet
(still running a small hack locally) but this is a nice example of
why I would like to see more OO capability. assume it was a forach loop
(I never use section, always seems awkward somehow):

------------->8-------------
<table>
{foreach name=i from=$items item=item}
	<tr>
		<td>{$item->name}</td>
		<td>{$item->price}</td>
	</tr>
{/foreach}
</table>
There items: {$items->basketCount()} {* takes quantities into account *}
Total price: {$items->getTotal()}    {* sums everything, discount aware *}
------------->8-------------

note $items is an object. :-)
