Slightly off-topic, but ...
Would you be interested in getting this back on topic? <evil grin>
... have a look at GRETA, my own regular expression template library. I have found it to be as much as 7x faster than boost regex. It's free for non-commercial use.
Does this mean that it (or something derived from it) couldn't be boostified?
I'd love any feedback you might have. The interface is not nearly as nice or as rich as Dr. Maddock's, but it's just about the fastest C/C++ regex library I've tested. Wide chars, backreferences, full Perl 5 syntax, etc., etc.
IMHO, it would be nice to have sort of regex light (less rich functionality, better performance) in boost, and GRETA might be a good starting point. It would be helpful if the parts of the interface common to both libraries were harmonized. Do you think this would be possible?
