Create a file with the following contents (here /tmp/destr.el):

;;; -*- lexical-binding: t; -*-
(require 'cl-lib)
(cl-destructuring-bind (&whole a b &rest _) '(1 2)
  (print (list a b)))

Then run

emacs -Q -batch -f batch-byte-compile /tmp/destr.el

The byte compiler will complain:

In toplevel form:
/tmp/destr.el:3:1:Warning: variable =E2=80=98_=E2=80=99 not left unused

even though the variable is clearly unused.
