Subject: Overriding to_s

Hi,

I'm playing around with ruby trying to understand whats going on, and
here is something I don't understand.

class ZNum
  def initialize(n)
    @n=n
  end
  def to_s
    self.class
  end
end

n = ZNum.new(1234)

puts n            # prints #<ZNum:0xb75dfcc8>
puts n.to_s     # prints ZNum

In both cases it uses ZNum#to_s, but the results are different. Why?
