  # Reading this file and wondering about the two tests with the same
  # name?  They're two alternate versions of the same idea. I've put
  # my choice second, because it will override the first
  # definition. So when the file is run, the first is ignored.
  #
  # That's not something I'd normally do. It's a side-effect of the
  # way code samples are included into the printed book.
