Subject: Struct class

The following code works fine (windows XP, Ruby 1.86)

Card = Struct.new(:rank, :suit)

class Card
  def to_s
    "#{rank} of #{suit}"
  end
end

c = Card.new(2, "hearts")
c.rank
>> 2

The following doesn't work:

Card = Struct.new(:rank, :suit)
class Card
  attr_reader :rank, :suit
  def to_s
    "#{rank} of #{suit}"
  end
end

c = Card.new(2, "hearts")
c.rank
>> nil

####################################

Any ideas why?
TIA,
ves
