Subject: What should I use instead of Generator in 1.9?

Hi,

I have been using Generator in 1.8, and now I need to port that code to
1.9.  My code looks essentially like the code below.  I'm confused as to
what the correct option is in 1.9: Fibers? Enumerator?
Enumerator::generator?  I'd like to know the simplest most
straightforward option possible, since I'm still a relatively novice
Ruby practitioner.

Any help gratefully received!

require 'generator'

def bar
   Generator.new do |g|
      (1..10).each do |number|
         g.yield number
      end
   end
end

@foo = bar

while true
   if @foo.next?
      if (number = @foo.next)
         puts number.to_s
      end
   else
      exit
   end
end
