-In most cases the [operators](https://github.com/clux/operators) module provides some must have additions to autonomy. It's referenced once above as `op`, and you can just do `$.extend($, require('operators'))` to import all the helpers onto autonomy's object.

 *This modules makes up the core part of the larger utility library*: [interlude](https://github.com/clux/interlude). If you find yourself extending with `operators` or `subset` a lot, you should use `interlude` instead (there's also more documentation included there).
