 Priority:  blocker                  |   Milestone:  MacRuby 0.5          
Component:  MacRuby                  |    Keywords:  class, instance      
-------------------------------------+--------------------------------------
 The mime-types gem has a class and an instance interface. The class
 interface uses an instance of itself. However, it doesn’t work in MacRuby.
 It does not seem to be initialised properly. I have included in a sample
 code with the expected behaviour. Changing @__types__ to @@__types__ will
 not fix it.

 #!/usr/bin/env macruby

 class Test
   def initialize()
         @foo = true
   end

   def add(something)
         puts "Is foo nil: #{@foo.nil?}"
   end

   @__types__ = self.new()

   def self.add(something)
         @__types__.add(something)
   end
 end

 t = Test.new
 t.add(3)
 Test.add(4)

 Output (MacRuby 0.5)
 Is foo nil: false
 Is foo nil: true

 Expected (Ruby 1.9.1/1.8.7)
 Is foo nil: false
 Is foo nil: false
