OK, although Set is really just a thin wrapper around Hash(*), and I 
find it easier to work with objects of one class instead of a two.

Regards,

Brian.

(*) example methods from class Set:

  def size
    @hash.size
  end

  def empty?
    @hash.empty?
  end

  def clear
    @hash.clear
    self
  end

  def to_a
    @hash.keys
  end

  def include?(o)
    @hash.include?(o)
  end

  def add(o)
    @hash[o] = true
    self
  end

  def delete(o)
    @hash.delete(o)
    self
  end
