+ * Syntax:

+
+ * Returns the value of the single name-value pair that appears in `input_object`.
+ * Arguments:
+    * `input_object` : an object value that consists of exactly one name-value pair.
+ * Return Value:
+    * The value of the single name-value pair that appears in `input_object`,
+    * `missing` if `input_object` is `missing`,
+    * `null` if `input_object` is null, or an empty object, or there is more than one name-value pair in `input_object`,
+      or any non-object value.
+
+ * Example:
+
+        object_wrap(
+                     {
+                       "id": 1
