This is absolutely a contrived example. $index is the equivalent to `var ctrl = angular.controller`, something that serves very well to communicate basic concepts but that you would never use in a real-world application. If you're dealing with server side data, your model should have a real unique key/id, and that is what you track by.

The amount of stuff in AngularJS that "serves very well to communicate basic concepts but that you would never use in a real-world application" is a huge problem with the framework. It's a perfect storm of a documentation site and blogosphere full of misleading and/or contradictory advice and examples, combined with conceptual and implementation complexity that makes it incredibly hard to just read the source and deduce best practices from first principles. This article contains a good example of the phenomenon: it suggests switching from `$timeout` to `setTimeout` with `$digest` to "give both frameworks the same information". Is that a silver bullet solution, or does it come with trade-offs, and if it does, what are they? I'm not sure, but my gut says that I shouldn't change this pattern in my code everywhere without doing a bunch of research to understand exactly what is going on. That's fine, researching how our tools work is a big part of the job, but I feel like Angular has a disproportionate amount of this sort of complexity compared with other tools I've used.
