Slightly simpler repro:
(defmacro foo bar
M-: (elisp--local-variables) RET
It fails here:
(`(lambda ,args . ,body)
(elisp--local-variables-1
(append (remq '&optional (remq '&rest args)) vars)
(car (last body))))
where it expects args to be a list, but it's the symbol
`elisp--witness--lisp'. I'm not quite sure what the correct fix is
here, so I've added Stefan to the CCs. :-)
