About the effort, do you really find the examples below with the new proposed syntax difficult to understand?
No. I just don't see how they would become tools I would use. My main interest here was in your claim to have economic applications, but the examples you give don't seem to offer big wins for the kind of calculations I, my students, or my colleagues do. Perhaps you will have better luck interesting/persuading others.
