+  ;; Parinfer uses `evil-define-key' without loading evil, so if evil is
+  ;; installed *after* parinfer, parinfer will throw up void-function errors.
+  ;; because evil-define-key (a macro) wasn't expanded at compile-time. So we
+  ;; make sure evil is installed before parinfer...
+  (package! evil)
+  ;; ...and that it can see `evil-define-key' if evil was installed in a
+  ;; separate session:
+  (autoload 'evil-define-key "evil-core" nil nil 'macro))
