+     * A utility function that converts an exception to a Status.
+     * Only call this function when there is an active exception
+     * (e.g. in a catch block).
+     *
+     * Note: this technique was created by Lisa Lippincott.
+     *
+     * Example usage:

+     *   Status myFunc() {
+     *       try {
+     *           funcThatThrows();
