While the re2 comparison might be interesting from an abstract standpoint, it intentionally supports a different regex language from Python so that it can run faster and use less memory. Since re2 can never replace Python's re module, it doesn't make sense to hold MRAB's new module to that standard. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
