@neauoire :: The thought process was somewhere along the lines how to show how data is fed into quotations.
Or how to render call: does it just span the quotation, or does it span the quotation + inputs.
I also know drop is not included in this language since the author didn't have a design chosen for it.
Interestingly, this notation can write code linear text can't directly express. Which was also where I was thinking combinators could be generated.
