Or: since the elements you're yielding are themselves also arrays, ruby 
can automatically assign them to individual variables if you wish (the 
so-called "auto-splat" feature)

films = [["one", "vol1"], ["one", "vol2"], ["three", "vol3"]]

films.each do |label, volume|
  puts "#{label}: #{volume}"
end
