It's a matter of how you conceptualize the optional trailing comma in tuples
other than 1-tuples.  If the rule is "a comma is permitted after the last
element", then "(,)" is illegal.  If the rule is "a comma is permitted before
the right parenthesis", then "(,)" is legal and means the same as "()".
(And the same reasoning for lists.)

As I say, I don't care how this one is decided.
