@Robert,

I was wondering about the whole approach, keeping in mind what Ryan 
suggested (drop class Record which apparently is silly, and loose 
dangling IO stuff). It strikes me that the simplest way to solve this is 
to create an external iterator as a mixin (O'Reilly, Ruby Programming 
Language, p 138). This is pretty much what you already suggested, 
without the foreach method, which I don't need.

module Record
  include Enumerable

  def each
    loop { yield self.next }
  end
end
