I think you meant 'something is equal to (quote something)? Because it is, right? These seem to be equal though the third perhaps doesn't make any sense in this example: (list 1 2 3) '(1 2 3) `(1 2 3) By the way I cannot find a &rest equality function in Elisp - perhaps there isn't any? That also brings about, when we say things are equal, by what function do we mean? There are so many of them you get dizzy: (= 1 1) (= 1 1.0) (eq 1 1) (eq 1 1.0) ; nil (eq 1.0 1.0) ; nil (?) (eql 1.0 1.0) ; t (eql 1 1.0) ; nil (equal '(1 2 3) '(1 2 3)) (equal "read this" (propertize "read this" :bold t)) ; t (equal-including-properties "read this" (propertize "read this" :bold t)) ; nil -- underground experts united
