If you mean on 2.7/3.2, then I guess we could extract the fixes from regex, but we have to see if it's doable and someone will have to do it.
Also consider that the regex module is available for 2.7/3.2, so we could suggest the users to use it if they have problems with the re bugs (even if that means having an additional dependency).
ISTM that current plan is:
* replace re with regex (and rename it) on 3.3 and fix all these bugs;
* leave 2.7 and 3.2 with the old re and its bugs;
* let people use the external regex module on 2.7/3.2 if they need to.
If this is not ok, maybe it should be discussed on python-dev.
