Fairly weak argument there :)

More notably, though: {0} {1} gives you stability, but {} {} gives you
simplicity. Use whichever one makes more sense. And if you're creating
localizable messages (where the template goes into a separate file and
the formatting happens a long way separate from it), you can take
flexibility even further by using {spam} {ham} and keyword arguments -
extremely helpful when you're reading through the message file.
