How do you say "ignore"?

Does anyone have a standard idiom that they use when ignoring variables
in a destructuring pattern in LOOP?

For example:

(DEFUN IGNORE-TEST ()
  (LOOP FOR (X IGNORE) IN '((A B) (C D))
	COLLECT X))

The way this is currently written the compiler will complain:

For Function IGNORE-TEST
  While compiling (SETQ IGNORE (CAR #:TEMP)):
    The variable IGNORE is unknown and has been assumed SPECIAL
