I can see how that might work for function-get:

    (defun function-get (f prop &optional autoload)
      ...
   +  (or
   +   (if (eq prop 'gv-expander)
   +       (alist-get f (alist-get :gv-expanders
   +                               (bound-and-true-p
   +                                byte-compile-macro-environment))))
       (let ((val nil))
         (while (and (symbolp f)
                     (null (setq val (get f prop)))
         ;; etc...

But how can I make function-put do the right thing for both a macro
calling it and keep it's normal role?
