This is a rather annoying regression, so I'd propose to fix it on the release branch. With Emacs 26: emacs -Q -batch -l cl-lib -l pcase -l rx -eval '(print (pcase "1" ((rx (? (= let foo digit))) foo)))' "1" (as expected) However, with Emacs 27 emacs -Q -batch -l cl-lib -l pcase -l rx -eval '(print (pcase "1" ((rx (? (= let foo digit))) foo)))' Unknown rx form =E2=80=98let=E2=80=99 In GNU Emacs 27.1.50 (build 9, x86_64-pc-linux-gnu, GTK+ Version 3.24.20) of 2020-11-09 Repository revision: f5d7fb3a2dee3f9ae49151e3d01483aad7fb734b Repository branch: emacs-27 Windowing system distributor 'The X.Org Foundation', version 11.0.12008000 System Description: Debian GNU/Linux rodete Recent messages: For information about GNU Emacs and the GNU system, type C-h C-a.
