According to pickaxe2, that is correct.  However, the anonymous class is 
called an 'anonymous' for a reason: it has no name.  So, what would 
obj.class return if that were to retrieve the name of the anonymous 
class?  nil?  I would imagine the anonymous class does not have a .class 
attribute, so the lookup for .class proceeds up the inheritance chain, 
something like this:


class Dog
  attr_accessor :name

  def initialize
    @name = "Rover"
  end

end

#-------------------

class IntermediateClass < Dog
end

#-------------------

class Puppy < IntermediateClass
end

p = Puppy.new
puts p.name

--output:--
Rover
