Dito! The last useful (and today widely used) syntax change in the 2.x
series was the 'with' statement. I don't see urgent need for any syntax
or language chances in the next couple of year. The only new feature I
can think of, that might require new syntax, is parallel processing and
executing multithreaded, GIL-less code. Such a feature is going to take
a long time before it's implemented.

I'm +1 on your proposal, Guido. Do you propose a fixed time span for the
moratorium or a status quo? Can we continue changing the language once
Jython and IronPython have fully implemented Python 2.7 / 3.2?
