Yes. This is almost what GtkBuilder does.

For vala gtype_instance classes, you may want to convert to either
some_type_name_new
or some_type_name_construct,
since you can't create these objects with g_object_new.

BTW: wouldn't it be nice if VALA automatically register all vala defined
types in either g_module_check_load or main?

Best,
