While that is true of the basic building blocks of the language, clojure.spec for example does have an overly verbose syntax (I would define it that way, even though it doesn't introduce new basic syntax elements) for function specs and that was one of the main motivations for writing Ghostwheel.

I wouldn't see this as some sort of development in Clojure though and I don't really know if that's what cutler meant anyway. Maybe he'll elaborate.
