 *     }
 *     foo ((NMType *) obj);

 *
 * Example 2:

 *     {
 *         access_obj_without_check (obj);
 *     }
 *     foo (NM_TYPE (obj));
 *     // There is a runtime check which prints a g_warning(), but that doesn't
 *     // avoid the crash as NM_TYPE() cannot do anything then passing on the
 *     // invalid pointer.
 *
 * Example 3:
 *     static void foo (NMType *obj)
 *     {
 *         g_return_if_fail (NM_IS_TYPE (obj));
 *         access_obj_without_check (obj);
 *     }
 *     foo ((NMType *) obj);
 *     // There is a runtime check which prints a g_critical() which also avoids
 *     // the crash. That is actually helpful to catch bugs and avoid crashes.
 *
 * Example 4:
 *     static void foo (NMType *obj)
 *     {
 *         g_return_if_fail (NM_IS_TYPE (obj));
 *         access_obj_without_check (obj);
 *     }
 *     foo (NM_TYPE (obj));
 *     // The runtime check is performed twice, with printing a g_warning() and
 *     // a g_critical() and avoiding the crash.
 *
 * Example 3 is how it should be done. Type checks in NM_TYPE() are pointless.

 * Note that in if the variant type would be invalid, the check still

 *   g_return_if_fail (g_variant_type_is_container (type));
