One of CoffeeScript's best features is the @ shorthand for this -- perfect for accessing instance methods and properties:

class Rectangle
  constructor: (@width, @height) ->
  getArea: ->
    @width * @height

But there's no similar shorthand for accessing static members, e.g. @@. So instead, you're forced to either hardcode class names, or type out the long constructor reference to be generic:

express = require 'express'

app = express.createServer()
# ...

module.exports = app
