I think this would be a good time to add a fourth example showing both the multi-language and parameterized rules features. It would be good to see these in a live example. The example languages could be two aspects of a system with a commonly used part of the syntax.

Rough idea: one language for a static view and another language for a dynamic view of a system, both sharing a common expression language.

A multi-language example was added with #676.

Note that we have an example for parameterized rules in our own grammar language:
