I think D needs into its std lib a RE engine as flexible and as fast as Python/Perl/Ruby/etc ones. (They use an "almost" standard syntax, you can do mostly the same things with them. People use the Perl REs every day).
Then later people can add any kind of faster & more specialized RE engines (like your one). Don't you agree? :-)
