My thought exactly.

OK, both patches are now up on the tracker.  The first patch, as
mentioned, does some internal refactoring that makes the policy
framework cleaner and adds hooks and a 'compat32' policy implementation
such that the current Python 3.2 behavior is preserved by default.

That's issue 14731: http://bugs.python.org/issue14731

The second patch adds a policy implementation (marked as provisional)
that adds the new header parsing and folding.  As of this patch only
'Date' type and 'Address' type headers are parsed as anything other than
Unstructured, but that's already worlds better than the compat32 policy.

That's issue 12586: http://bugs.python.org/issue12586

I would appreciate reviews of both patches, even cursory ones.  This
split up should make them as easy to review as such big patches can be:
the goal of 14731 is 100% backward compatibility, so a review can focus
on making sure that the tests match the Python 3.2 tests (with some
additions for bugs fixed).  125867 then adds a bunch of new code that
can be evaluated on its own merits.

Absent objection from patch reviewers, my plan is to apply these patches
before the next alpha (which is scheduled for May 26th, ie: next weekend).
