Hi,

Consider the following

(pcase-dolist (`(,(and (pred stringp) a) .
		 ,(and (pred stringp) b))
	       '(("TODO") ("DONE" . "a")))
  (warn "%S :: %S" a b))

Executing the above yields

⛔ Warning (emacs): "TODO" :: nil
⛔ Warning (emacs): "DONE" :: "a"

even though ("TODO") does not match the pattern.

In contrast

(dolist (el '(("TODO") ("DONE" . "a")))
  (pcase el
    (`(,(and (pred stringp) a) .
       ,(and (pred stringp) b))
     (warn "%S :: %S" a b))))

correctly displays

⛔ Warning (emacs): "DONE" :: "a"
