  "A foolish consistency is the hobgoblin of little minds."  -rwe

  "a b c".split(" ") makes sense.  " ".join(("a", "b", "c")) does, too.
("a", "b", "c").join(" ") might make sense, but it would also involve
writing a pile more code, and reducing the usefulness of the operation.  So
why aim for consistency, when we can achieve usefulness instead?
