Strong agree. The syntax in this work was meant to be mostly hidden from the end user. I've found that syntax is still really useful for language design and implementation. I stopped before building the graphical programming environment on top.

Designing a productive graphical programming environment is very challenging. I think it is probably at least as difficult as designing the underlying language mechanics. I'd love to see any experiments you might be able to share.
