Hmm... output optional content or an entirely different rendering for the first object or last object? In my case (www.thedailytube.com) the first object rendered is highlighted with a bigger image and more text of the description displayed. In an email application your thread page you might only want to show the full contents of the last entry and minimized entries for the rest.
Currently I'm just testing _index == 0 from within my component, but it'd be handy if I didn't have to define the _index and could just call _loop.getIsFirst() when picking CSS, or <t:if test="loop.isFirst"> when selecting the components to render. I think that creating a simple delimited string is something that should be easy to do, but I don't think it makes sense to tack it on to the loop component. It'd be better to make it trivial to write your own component, or use the features of the component to get that effect.
