3.2 Making declarations

3.2.7 IGNORE declarations

Anignore declaration prevents the Compiler from issuing a warning when the variable specified in the declaration is not referred to in the body of the code. For example, the Compiler will not produce a warning about the variableslies andhalftruths when the following code is compiled:

(defun just-the-facts (case)
  (multiple-value-bind 
      (lies halftruths facts)
    (case-report case)
    (declare (ignore lies halftruths))
    facts))
