Guido has stated that the parens are only required to disambiguate the 
expression. The main case that's out of the ordinary (ie currently there are 
situations where we need to disambiguate expressions, and this is a new one) 
is where one of these conditional expressions occurs at the start-of-line. 
The "if" is then a statement unless forced to be an expression. And without 
the parens, a SyntaxError will result.
