Does this mean that it (or something derived from it) couldn't be boostified?

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?
