I think that's just because it's C++ though. I'd bet a D lib that worked the same way would probably do a lot better. In any case, I started writing a comparison of the main fundamental differences between Spirit and Goldie, and it ended up kinda rambling and not so just-the-main-fundamentals. But the gist was: Spirit is very flexible in how grammars are defined and processed, and Goldie is very flexible in what you can do with a given grammar once it's written (ie, how much mileage you can get out of it without changing one line of grammar and without designing it from the start to be flexible). Goldie does get some of that "flexibility in what you can do with it" though by tossing in some features and some limitations/requirements that Spirit leaves as "if you want it, put it in yourself (more or less manually), otherwise you don't pay a price for it." I think both approaches have their merits. Although I haven't a clue which is best for Phobos, or if Phobos even needs either.
