Dammit yes, you’re right! Well, it’s not a bit less confusing.
The most frustrating is that they have a point: we need to be stricter about disambiguating functions and numbers, and derivation really should be an operator.
But you don’t need to go all the way to zero-indexing (which is definitely not a thing in the fields I know) or positional arguments. This is putting abstract notation purity above practical concerns. It’s not surprising they like Scheme.

In fact one of the authors, Gerry Sussman, is one of the original inventors of Scheme. https://en.wikipedia.org/wiki/Gerald_Jay_Sussman https://en.wikipedia.org/wiki/Gerald_Jay_Sussman
