That's not really true, although the syntactic compatibility does make for conveniently trivial cross-compatible code, Python 3 did not "remove the old, braceless version" it converted exec from a keyword (which could accept a single tuple parameter) to a builtin function (which takes up to 3 parameters). Which had the side-effect of requiring parenthesis.

Incidentally, the print-tuple-trick is cute, I hadn't considered it.

Yes, I explained badly. I appreciate the clarification.
