Re: A question about ignoring IGNORE
From: Jeffrey Mark Siskind <Qobi@ZERMATT.LCS.MIT.EDU>
as the old saying goes, how do I avoid being "Damned if you
do, and damned if you don't"? What I really want is something
like (DECLARE (I-DONT-CARE-IF-IT-IS-UNUSED FOO)).
In our signal processing environment we simply list the variable as
a form in the function. Thus a lot of our automatically generated code
(defun user-routines (arg1 arg2)
arg1 ; Just in case user doesn't reference it
arg2 ; Just in case user doesn't reference it
(...the code supplied by the user...))
So far this has worked (without any noticeable degradation in performance)
in Symbolics, Lucid and Franz Common Lisp.
