Getting to class variable from instance of Class in CoffeeScript

Question

I have a class like this:

class Cow
  @feet : 4

  constructor: (@name) ->

bes = new Cow "Bessie"

The question is, is it possible to access feet only given bes?

You can use the JavaScript constructor property to get at the class and there you will find your feet:

class Cow
    @feet: 4
    constructor: (@name) ->

class HexaCow extends Cow
    @feet: 6

bes = new Cow('Bessie')
pan = new HexaCow('Pancakes')

alert(bes.constructor.feet) # 4
alert(pan.constructor.feet) # 6

I don't know of any special CoffeeScript replacement for constructor though.
