Thanks for this interesting write-up on AST-based editors. Smalltalk has some of these ideas, and you might want to have a look at TexMacs (even though the project is abandoned). Like you, I feel that linear text-based editors are severely holding us back in communicating our intentions and inventions. I've had very similar ideas myself and even worked shortly on a Lisp which recursively forms an editor for itself (using a meta-object protocol).
