♨ Sugar.js your CoffeeScript

I encourage you to use sugar.js in your application (but not library) as an alternative to underscore.js. It'll make your code clean, especially if you're using CoffeeScript.

One concern is polluting prototypes of native objects, but Sugar.js leaves Object's prototype intact, and in practice methods it adds to other natives will never break other code.

Additionally, if you're messing with JavaScript Date and Time objects, I suggest using date.js (it has awesome and Sugar.js-compatible API).
