Subject: Unable to print a block argument.

I am doing some experiment with ruby and I am not sure why the #len
method is not returning the length of the object that I created from
Foo.

class Foo

  def self.open(test)
    x = new test
    block_given? ? yield(test) : test
  end

  attr_accessor :op

  def initialize( op  )
    @op = op
  end

  def len
    @op.length
  end


end


Foo.open("this") { |o| puts o.len }
