Well, the details remain to be finalized but the general idea is a generator DSL. Think of HAML in regards to HTML for example: you can write nice DSL-specific code that gets translated into valid HTML code. (There is already a relevant module for that for Arturo, thought at a very experimental level: https://github.com/arturo-lang/art-html-module).

I'm thinking of the same thing for LaTeX (and perhaps even more sophisticated). One of my main "businesses" is centered around typesetting and electronic publishing, hence I'm a heavy ... LaTeX user.

Feel free to ask anything else. All suggestions and contributions are welcome! :)
