Your second sentence doesn't necessarily relate to your initial
question :-) Meaning: whether instance vars are private or not,
there's no reason to think that every instance var is going to have
one of these:

  def var
    @var
  end

associated with it.  All sorts of other permutations are
possible... including no accessor method, or this:

  def var
    @thing
  end

or this:

  def var
    @var * 2
  end

etc.
