I stand by "parens don't make a tuple", with the caveat that I should
have mentioned the empty tuple exception that proves the rule. The only
time you need parens is to resolve ambiguity.

To suggest that parens do make tuples confuses the issue, given things
like this:
>>> a = 1,2,3
>>> b = (1, 2, 3)
