EuroPython 2011 Language Summit =============================== [...] Unicode character classes is a particular need). [Subtopic: what needs to be done to get the new regex module into Python?

What about backwards compatibility issues?] I'm pretty sure regex has backward compatibility as a goal for just this reason (so it can replace the current module).
The new regex library has some great improvements:
This issue is open since April 2008, has also the longest list of attached files, and has a very long history. What is the status of the issue? I see that there is now a third party project on:
This should be the same module as in the issue (and thankfully, because code management of such a big project does not belong exclusively in a tracker issue). "mrab" stands for Matthew Barnett, who is the author of regex.

There is also the re2 library from Google and especially this project:
http://pypi.python.org/pypi/re2/
"pyre2 is a Python extension that wraps Google's RE2 regular expression library.
This version of pyre2 is similar to the one you'd find at facebook's github repository except that the stated goal of *this version is to be a drop-in replacement for the re module*.)"
Well, while it can be called drop-in, it is hardly a good replacement: """ That being said, there are features of the re module that this module may never have. For example, RE2 does not handle lookahead assertions ((?=...)). """ It falls back to old re in these cases. Georg
