Why doesn't this code work?

animals = %w(narwhal octopus wallaby worm)

for animal in animals
    puts "The current animal is #{animal}"
    retry if animal == 'octopus'
end

I can't see anything wrong with it, yet the retry line produces an error....?!

Ah, it's because the video is out of date. In the current Ruby (around 1.9.3 now), you can't use retry like this. I'm moving on to the next video.

Would be nice to have this updated!

Just to get this out of the unanswered section, this is true 'retry' can't be used outside of a rescue block.

But you can use 'redo' if you want the same functionality. That's what I've read anyway. I haven't really tested it out myself. Might make a good experiment for you.
