Sorry I did not read as closely as I should -- my example was just of
a "break," if you are after next/continue functionality, you need to
put the catch/throw inside the outer loop:


(0..10).each do |i|
  puts i
  catch :deep_error do
    (0..10).each do |j|
      puts j
      (0..10).each do |k|
        puts k
        throw :deep_error if 2 == k
      end
    end
    puts "never going to happen"
  end
end
