Agreed! So let's think about it some more. :)

I tend to use parens around tuples frequently, but not always:

a, b = b, a

x, y, z = foo()

And so on. I don't tend to use parens in the context of tuple unpacking,
but elsewhere, I do. Partially because in those contexts I tend to *need*
parens to disambiguate:

def foo(1, 2) versus def foo((1, 2))
[1, 2] versus [(1, 2)]
