Their might be an under-explored middle ground here, somewhere between representing a program as ASCII text and a full blown graph ZUI. Language is already a very efficient way to layout a graph structure, so lets keep that and borrow from maths the notation for summation, integration, ect, and from physics maybe Dirac's bracket notation for matrixes. I have thought of doing somethings like that in the browser with a WYSIWYG editor (document.designMode='on') and web components. The DOM is like the AST of the program and is fed into a runtime. Non-expression tags are basically just comments. Not for regular programming, but for a type of scientific notebook interface to do exploratory programming. Anyway one of this days.
