Yes, I've been down this rabbit hole before :)

I'm not just looking for static includes, but dynamic, real-time, editable includes built in to a framework that uses a single syntax to describe a full web app. I'm tired of using full programming languages for describing app data — and how it can be edited — when so much of what a web app can do has already been implemented a billion times.

PHP is great for that, but, in my opinion, is 500% more powerful in areas that don't count (low-level language constructs that make it Turing complete, but not ideal for building real-time, editable web apps) and 10% as powerful as it should be in areas that do count (i.e. performing higher level tasks automatically, like structuring data, syncing data between pages, moving data around, rendering data to the page easily, etc.).
