Subject: [PATCH] Add the public API of Compat to the core

* lisp/emacs-lisp/compat.el: Add stub file with minimal definitions,
so that core packages, that haven't been installed from ELPA, can make
use of the public API and use more recent function signatures.
* lisp/progmodes/python.el (compat): Remove 'noerror flag, because
Compat can now be required without the real package being available.

+
+;;; Commentary:
+
+;; The Compat package on ELPA provides forward-compatibility
+;; definitions for other packages.  While mostly transparent, a
+;; minimal API is necessary whenever core definitions change calling
+;; conventions (e.g. `plist-get' can be invoked with a predicate from
+;; Emacs 29.1 onward).  For core packages on ELPA to be able to take
+;; advantage of this functionality, the macros `compat-function' and
+;; `compat-call' have to be available in the core, usable even if
+;; users do not have the Compat package installed, which this file
+;; ensures.
+
+;; Note that Compat is not a core package and this file is not
+;; available on GNU ELPA.
+
+;;; Code:
+
+(defmacro compat-function (fun)
+  "Return compatibility function symbol for FUN.
+This is a pseudo-compatibility stub for core packages on ELPA,
+that depend on the Compat package, whenever the user doesn't have
+the package installed on their current system."
+  `#',fun)
+
+(defmacro compat-call (fun &rest args)
+  "Call compatibility function or macro FUN with ARGS.
+This is a pseudo-compatibility stub for core packages on ELPA,
+that depend on the Compat package, whenever the user doesn't have
+the package installed on their current system."
+  (cons fun args))
+
+(provide 'compat)
+;;; compat.el ends here
