Author here. I had a simple, generic idea for a way of structuring code editors that doesn't require parsing (even though the appearance can still be 100% text), and I've been trying to get feedback from folks who know more than myself on the limitations it might have which I don't see yet, before I go ahead and spend a ton of time building an instance of it.
I'd be happy to answer any questions and to hear your analyses!
Edit: also, if you are very familiar with this domain already, you can probably just look at the series of images depicting this scheme for constructing program models (as well as the sample program model '(2 2 0 1 3 0 0 3)'—and that will probably be sufficient.
Smalltalk in General and Scratch in particular take several steps in the same direction. There are clear advantages to not having to deal with the impedance mismatch, same as for dropping SQL and using database primitives. Depending on implementation choices (serialization format etc) you're trading more or less interoperability to get there.
