View/controller separation, view models and query abstraction are framework-level features. The author of this language is seeking to take the qualities of PHP that make it a 'hypertext preprocessor' and mixing in the no-frills syntax and vocabulary of ruby or python.
I don't understand why you wouldn't just use a framework like Sinatra. It's simple in every way that qualifies it to contend with a 'hypertext preprocessor'. Add it to your gem file, bundle, git commit, push to heroku, deployed! It even has inline templates[1].
You could argue it has a learning curve, but is resistance to learning a good argument against a solid & simple, versatile framework?
