a simple getter and setter in coffeescript mimic attr_accessor of ruby (monkey patching version)

attr_accessor.coffee

Object::attr_accessor= (prop) ->
  self=@
  self["_#{prop}"]=null
  self[prop]=(value) ->
    @["_#{prop}"]=value if value?
    @["_#{prop}"]


Player={}

Player.attr_accessor("name")

Player.name("mario")
alert Player.name()

cool! :-)
