[antlr-interest] Generating text from models

[Oliver Zeigermann]

Hi Mike!

I see Xpand as a combination of a template language and tree walker.
You both specify how to walk the model and which data is emitted in
which template slot. So: Why not combining ANTLR tree grammars with
template output rules? Same thing.

But: How to create the model (=AST)?
