How about a keyword named "rest", with parens around the keyword and
variable identifier? The parens emphasize to human readers that the
"rest" name is in a keyword position and therefore should not be
mistaken for a variable identifier?
(let ( (a b c d (values 1 2 3 4)) ) c) ;=> 3
(let ( (a b (rest x) (values 1 2 3 4)) ) x) ;=> (3 4)
(let ( ((rest x) (values 1 2 3 4)) ) x) ;=> (1 2 3 4)
(let ( (a b (rest x) (values 1 2 3 4)) ) x) ;=> (3 4)
(let ( (a b (rest rest) (values 1 2 3 4)) ) rest) ;=> (3 4)
