    /* The cast macros like NM_TYPE() are implemented via G_TYPE_CHECK_INSTANCE_CAST()
     * and _G_TYPE_CIC(). The latter, by default performs runtime checks of the type
     * by calling g_type_check_instance_cast().
     * This check has a certain overhead without being helpful.
     *
     * Example 1:
     *     static void foo (NMType *obj)
     *     {
     *         access_obj_without_check (obj);
     *     }
     *     foo ((NMType *) obj);
     *     // There is no runtime check and passing an invalid pointer
     *     // leads to a crash.
     *
     * Example 2:
     *     static void foo (NMType *obj)
     *     {
     *         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.
     * Disable them for our production builds.
