A big +1 from me.  I'm all for putting it in Python 3.2 alphas and beta1 as
a *replacement* for the existing 're' module in order to get it visibility
and a shakeout and make this available to the world sooner rather than
later.  This module was designed for compatibility for exactly that reason.
 Lets give it a high publicity fair shake it iron out any unknown
compatibility issues early on so that we can decide how to proceed.

Also, +1 to Antoine's point on volunteering to be the maintainer of it for
the next couple major releases.

(I do expect someone to balk at this idea with "but python 3.x doesn't have
enough users yet for a beta cycle to shake out hidden regular expression
engine assumption bugs" to which I'll respond in advance with "thats a good
thing; we can add a regular expression sniffer to 2to3 that flags potential
problems in code being ported over")
