I give this approximately 0% chance of happening. It's a really
complex change to the syntax and code generator. Your motivation is
also suspect: 2.6 is supposed to be a stepping stone towards 3.0, not
a safe haven for people who don't like certain 3.0 features. Just get
used to print(). Parentheses for exceptions has been allowed since
approximately Python 2.0, so you have even less of an excuse there.
