Usage

(let ((expected '(:a :b :c))
      (actual '(:a "b" :c)))
  (diff-print (mismatch-sexp actual expected)))

(let ((expected "Common Lisp is awesome!!")
      (actual   "Common lisp is awesome!!"))
  (diff-print (mismatch-sexp actual expected)))

(let ((expected (alexandria:plist-hash-table '(:a "a" :b "b" :c "c")))
      (actual (alexandria:plist-hash-table '(:b :b :c "c" :d "d"))))
  (diff-print (mismatch-sexp actual expected)))

As the name shows, MISMATCH-SEXP is for S-Expression, i.e. macroexpanded form. Please note about uninterned symbols are treated as the same as expected. (In corner cases, this behavior may be the pitfall though.)

(let ((expected (macroexpand-1 '(with-open-file (s "path") (read s))))
      (actual (macroexpand-1 '(with-open-file (out "path") (read out)))))
  (diff-print (mismatch-sexp actual expected)))
