CoffeeScript缩进错误

Question

知道为什么在编译时会出错？

(window) ->

    # pubsub
    App.publish = (topic,args) ->
        App.subscriptions[topic] and $.each(App.subscriptions[topic], ->
            this.apply(App, args or [])

没关系，我很傻，忘了删除paren：\

（窗口） - ＆gt;

# pubsub
App.publish = (topic,args) ->
    App.subscriptions[topic] and $.each App.subscriptions[topic], ->
        this.apply(App, args or [])
