Example: SELECT

Note that the backquote doesn’t have to be at top-level. Also note the use of the dot (.) which means that the list that follows should be spliced into the current list.

(defmacro select (object &rest clauses)

(append '(cond)

(mapcar

#'(lambda (clause)

`((equal (first ',clause) ,object)

. ,(rest clause)) )

clauses)))
