call static properties of the current class in coffeescript

1_reference_class_by_name.coffee

class A
  @temp: 'A'
  constructor: () ->
    console.log A.temp
    
class B extends A
  @temp: 'B'
  constructor: () ->
    super
    console.log B.temp
    
b = new B()

# outputs 'A', 'B'
# intended output, but not really nice with all the named-references

2_this_constructor.coffee

class A
  @temp: 'A'
  constructor: () ->
    console.log @constructor.temp
    
class B extends A
  @temp: 'B'
  constructor: () ->
    super
    console.log @constructor.temp
    
b = new B()

# outputs 'B', 'B'
# not the intended output

3_solution.coffee

class A
  @temp: 'A'
  self = @ # @ = class, not this (the instance)  
  constructor: () ->
    console.log self.temp
    
class B extends A
  @temp: 'B'
  self = @ # @ = class, not this (the instance)
  constructor: () ->
    super
    console.log self.temp
    
b = new B()

# outputs 'A', 'B'
# intended output, pretty ok syntax

In case anyone stumbles upon this, #2 works in modern CoffeeScript (tested with v1.10.0) as it should. You should be using @constructor to get a reference to the ‘class’.
