Here are the suggestions, so far:

        else
        ensure
        finally

I agree Jonas: it would be nice to have 'else' mean 'if the loop was never 
entered'; EG:

  for x in some_array
    # ...
    break if x == foo
  else
    puts "The array was empty"
  finally   # or ensure, which is already a Ruby keyword
    puts "x was foo!"
  end

I don't know when I'd ever use 'finally', but I can think of many cases 
where the 'else' would have saved me some time.
