Style qeustion: Multiple return values

[Steve Keller]

Just a short style question: When returning multiple return values, do
you use parenthesis?

E.g. would you write

    def foo():
        return 1, 2

    a, b = foo()

or do you prefer

    def foo():
        return (1, 2)

    (a, b) = foo()
