I quote: "This PEP proposes a temporary moratorium (suspension) of all changes to the Python language syntax, semantics, and built-ins for a period of *at least two years* from the release of Python 3.1." Emphasis mine. Like I say, a definite end point would be much preferred to n > 2. If possible, I'd also like to hear some of Steven's other points addressed.
