I agree that zero-length and singleton tuples don't make a great deal of
sense semantically. But by now there's been enough tuple-abuse that the
general wish is to have tuples behave exactly like lists.
Of course the singleton tuple was more or less bound to exist once the
DB API started returning result rows as tuples, and I suspect that them
empty tuple is an acceptable generalization.
