No, that results in a circular import.

The way this file (not my code, by the way) seems to work is that it
started out as one file, org-fc.el, that contained everything. At
various points, they decided to break out some parts of the file into
separate files like this:

```
;;; org-fc.el

;; ... some definitions, including macro
`org-fc-with-point-at-back-heading' and the other `org-fc' symbols
mentioned in org-fc-type-normal.el

(require 'org-fc-type-normal)

;; ... some more definitions

(provide 'org-fc)
```

```
;;; org-fc-type-normal.el

(defun org-fc-type-normal-init ()
  "Mark headline as card of the normal type."
  (interactive)
  (org-fc--init-card "normal")
  (org-fc-review-data-update '("front")))

(defun org-fc-type-normal-setup (_position)
  "Prepare a normal card for review."
  (interactive)
  ;; Make sure the card is collapsed
  (outline-hide-subtree)
  (when (org-fc-has-back-heading-p)
    (org-show-entry)
    ;; Make sure the back heading is visible
    (org-fc-with-point-at-back-heading
     (org-show-set-visibility 'minimal))))

(defun org-fc-type-normal-flip ()
  "Flip a normal card."
  (interactive)
  (org-show-entry)
  (org-show-children)
  ;; NOTE: the body only runs if the card has a back heading
  (org-fc-with-point-at-back-heading
   (org-show-entry)
   (org-show-children)
   (org-fc-show-latex)))

(org-fc-register-type
 'normal
 'org-fc-type-normal-setup
 'org-fc-type-normal-flip
 'org-fc-noop)

;;; Footer

(provide 'org-fc-type-normal)
```

Note that `org-fc-type-normal.el` doesn't `require` anything from
`org-fc`, but assumes that they have been already defined by the time
`org-fc.el` runs the `require` call.
