I've been wanting to check out Antlr (www.antlr.org) because it gives us the /possibility/ to use the same grammar files for both CPython and JPython. One problem though is that it generates Java and C++ so we'd be accepting our first C++ into the core if we went this route.
Or contribute a C back-end to ANTLR -- I've been toying with this idea for, ummm, too damn long now. Years.
