I wonder if we could come up with a more generic way to solve similar problems? This syntax is similar to other template languages — Liquid, Nunjucks, etc.

11ty has a concept of markdownTemplateEngine that adds a template language processor on top of markdown. Maybe it's something like that? But maybe instead of doing something so opinionated, we find a way to open it up?

Or do we solve with documentation/examples for now?

I was wondering how to square these two.

The primary use case for me was having access to functions like

import { allFoos } from 'contentlayer/generated'

so I could generate dynamic navigation.
