PubSub method using coffeescript classes and jquery's callbacks

feed.coffee

class @Feed
  constructor: (@func)->
    @callbacks = $.Callbacks()
  init: ->
    @subscribe( @func )
  subscribe: =>
    @callbacks.add( @func )
  publish: (args)=>
    if args.length < 1
      @callbacks.fire @func
    else
      @callbacks.fire @func.apply @, args

usage.coffee

init: ->
  #instantiate a new feed and pass the function to subscribe
  @nameOfFeed = new Feed( @someFunction)
  
someFunction: (arg1)=>
  console.log "the argument is " + arg1
  # output: "the argument is successful"
  
otherFunction: =>
  #doSomething here, on success
  @nameOfFeed.publish [ 'successful' ]

Updated tonight to include the ability to pass in an array of arguments with the .publish() function that will be applied to the subscribed function on execution.

This still lacks the ability to subscribe multiple functions, or to remove subscribed functions.
