Somehow this looks familiar - do you have still the link?

Hmm - I don't see how that compiler does help with ANTLR code generation.

Why is the normal action syntax not enough? Isn't the content of actions largely left alone? And even if there is some problem one could use partial classes to define LINQ queries in separate methods. This is a good idea anyway for better syntax highlighting.
