This is probably out-of-the-question, but here it goes: Have you looked into if antlr3 could help us in anyway ? One thing I understood from their release notes is that they now have a clear distinction between generationtime and runtime resulting in a smaller footprint and easier isolation. > 2) Adding the notion of a component "persister".
