		It is worth noting that this functionality only applies to functions. If an object has a $ prefix, then any functions inside that object will be crunched by `clues` as usual.
		It is worth noting that this functionality only applies to functions. If an object has a $ prefix, then any functions inside that object will be crunched by `clues` as usual.

		If you would like to have a service method that is partially fed by the rest of the `facts`, you can name your function `$prep`. If you want to make a `$prep` for your service, you must eventually return a `$service` method. For example:

		```js
		var Cabinet = {

		something: () => 5,
		complicated: () => 6,

		$adder: function $prep(something, complicated) {
		let work = something + complicated;
		return function $service(number) {
		return work * number;
		}
		}
		};
		```
