Yes, it's been brought up here, on python-dev and python-ideas several times in the past year and a half. > Are there any plans to speed up Pythons regular expression module ? > Or > is the example in this artricle too far from reality ??? I don't think anyone has taken any concrete steps towards re-writing the regular expression module. My understanding from previous threads on the topic is that the core developers would be willing to accept a re-written regular expression engine, but none of them are interested in doing it themselves. The general consensus seemed to be that the pathological cases hilited in that article are not very common in the real world, and that simply switching to the alternative approach advocated there would require giving up things like backreferences that are actually used in the real world, which is probably unacceptable.
