As I stated in the Ruby Conference, official answer for this request is:

  use catch and throw.

Like the following.

  catch (:matched) do
    for i in 0..5
      for j in 5..8
        if i == j
          throw :matched
        end
      end
    end
  end

  if i == j
      print "match\n"
  else
      print "nomatch\n"
  end
