(doc get) returns
"-------------------------
clojure.core/get
([map key] [map key not-found])
Returns the value mapped to key, not-found or nil if key not present."
As 'get' works for a vector, as well as a map, I think the function addresses the associative abstraction, so this format would be less misleading:
([associative key] [associative key not-found])
Thanks to the experts at ClojureVerse who confirmed that my confusion at the example was justified and suggested I report it here.
