Reopened because definitely regex will be not adopted in 3.5.

Here is updated to 3.5 Jeffrey's patch.

I have finished work on the Atomic Grouping / Possessive Qualifiers 
support and am including a patch to achieve this; however, 
http://bugs.python.org/issue2636 should be consulted for the complete list 
of changes in the works for the Regexp engine.

Jeffrey C. Jacobs [EMAIL PROTECTED] added the comment:

Quick update (see thread 2636 for other updates to the Regex
functionality): I do have a design in my mind for how to accomplish both
Atomic Grouping and Possessive Qualifiers and it would work with either
the existing Engine design or the new design I have been playing with. 
It's just a matter of getting around to implementing it, testing it and
documenting it.

I currently am having problem with Bazaar / Launchpad which are beyond
the scope of this issue but are effecting my work.  Those issues can be
found on the Launchpad site if you look for Answers / Bugs originating
from timehorse.

Jeffrey C. Jacobs [EMAIL PROTECTED] added the comment:

I'm digging into the sre_parse.py at the moment and this I have all the 
changes I need for that now.  The rest of the changes I believe are in 
either sre_compile.py or more likely directly in _sre.c, so I will 
examine those files next.  I am attaching a single diff for 
expedience.  This is not an official patch, just a sample to see the 
progress I am making.  I forgot the correct format for patch files but 
I promise to get it right when I have made more progress.
