Perhaps this could be addressed by requiring "from __future__ import
decorators", for one release, just like was done for "yield".  I
expect that this would be acceptable to the ObjC folks, too.  It
wouldn't be my favorite, but I won't rule it out just because of the
new keyword (and yes, this is a softening of my position on new
keywords).
