Would like to be able to do something like:

<div *ng-for="var item of items">
      <div [class.selectable]="$last">Foo</div>
</div>

    Just to clarify, you can do var items of items, var last = items.length - 1 today, right?

    Also, this makes sense for a List, but what if it is an Iterable and doing a length calculation is expensive?

    For an iterable, this would be true if hasNext is false. The length approach wouldn't work for iterables. A workaround that we're using right now is item == items.last, but this has issues if equals is overridden.
