That's because adding to the end of a Lisp list is a *bad* idea.

Your better option usually is to avoid doing that by keeping your list
in reverse order while you add elements to it and to reverse it at the end.

    (cl-callf PLACE (lambda (xs) (append xs (list VAL))))

while `push` is constant time, the above has O(N) complexity.
