Backbone.jsをCoffeeで書いた時のEventsの継承の仕方 ref: http://qiita.com/items/14050e79df746b51d28c

file0.coffee

# model
class Hoge extends Backbone.Model
    constuctor: ->
        super
        @set fuga: 'fuga'

# View
class HogeView extends Backbone.View
    constuctor: ->
        @model = new Hoge
        super
    fuga: ->
        @model.get 'fuga'

file1.coffee

class EventDispatcher extends Backbone.Events

# でもインスタンスを作ってみると
dispatcher = new EventDispatcher
console.log dispatcher.on # -> undefined

file2.coffee

# これが公式の方法
dispatcher = _.extend {}, Backbone.Events

# もしくは別の方法でこんなのとか
dispatcher = _.clone Backbone.Events

file3.coffee

class EventDispatcher
    # ここでprototypeに無理やり継承させる
    _.extend @::, Backbone.Events
    fuga: null
    piyo: null
    constructor: ->
        @fuga = {}
        @piyo = []

# これで継承できてる
dispatcher = new EventDispatcher
console.log dispatcher.on # -> function (...) {...}
