[Ecls-list] Object found in array but not used

[Matthew Mondor]

I also fail to understand the meaning of this new warning.  Under such
a warning a line is shown (a list to show more details), but I fail to
see where a problem lies.

Example generating the warning:


(defun foo (&key (def :bar))
  (unless (member def '(:foo :bar :baz :quux))
    (error "DEF should be one of :FOO :BAR :BAZ :QUUX"))
  def)

(compile 'foo)


Thanks,
