Hi,

seems not to work neither


------------------
def add(object)
    name = "@" + self.collection_name_for(object)

    if self.instance_variable_get(name)
      self.instance_variable_get(name) << object
    else
      self.instance_variable_set(name, Array.new)
      self.instance_variable_get(name) << object

      class << self
        define_method(name) do
          instance_variable_get("@#{name}")
        end
      end

    end
  end
------------------
in `define_method': interning empty string (ArgumentError)
