Racket provides syntax for doing this. The evaluation for quoted objects is that a quoted object evalutes to itself. ‘x => ‘x (list elmer fudd) => error! elmer isn’t defined (list ‘elmer ‘fudd) => ‘ (elmer fudd) (elmer fudd) => error! elmer is an unknown function ‘ (elmer fudd) => ‘ (elmer fudd) (equal?
