Python core devs should write the 'python_next' and 'is_python_code' parts that moves source code from the current version to the next if a backwards incompatible grammar change is needed.
Python programmers may use the helpers to upgrade to the next version. > I don't know what part of the current code (current code of *what*?) is > supposed to be upgraded or evolved, or what you mean by that.

(instead of '2to3' a kind of 'nowtonext', aka 'python_next') Couldn't that relax the tension on doing 'backward compatibility changes' a bit ?
