More Array Conditionals in Templates

Xiph

These two conditions would be particularly useful:

True if the current iteration is the n-th interation (rather than just @first and @last)
True every n iterations, for example:

1st iteration: false
2nd iteration: false
3rd iteration: true
4th iteration: false
5th iteration: false
6th iteration: true
7th iteration: false
etc. etc.

I'm not too sure if we should be adding too much logic in the templates (gets super messy). That said, there is a way for you to accomplish the above, via helpers.

JS:

templates.registerHelper('iterateFn', function(data, iterator, total) {
    return (data.someVar && iterator === 3) ? true : false;
});

Templates:

<!-- BEGIN someLoop -->
{function.iterateFn}
<!-- END someLoop -->

Some real-world examples found here (none using the iterator variable as of yet though)
