Now that the parsing bits are fairly well defined, I decided on making a semi-sizable test grammar. Now done is the Lexical parts of C# 2.0 (minus a few things like unicode escaping, pre-processor stuff and @keyword identifiers). Works out of the box too. It's pretty slow (~3 seconds for helloworld in release 10+ mins! in debug) but I think that might have to do with the explicitness of the grammar.

Still, runtime speed's not the point. Easy to use, quick to implement grammars, and I get some valuable experience.
