the rest.

cons is acting according to its documentation.
Some of the roles played by lists in other Lisps are played by seqs in
Clojure. Also, in Clojure a list is not a linked list of cons cells.
Roughly speaking, a Clojure list is a linked list of lists:
user=> (list? (rest (rest (rest '(1 2 3 4 5 6 7))))) true --Steve
