gobject has fine type checking mechanism pcb just doesn't use it.  It wouldn't
be worth it at all because as lisp/duck type proponents point out type errors
aren't actually a problem in practice at least for programs pcb size.
Admittedly
gobject types are a pain to use but it's really not much worse than C++ where
you need two parallel object structures one with pointers and then the
same thing
over again with refs.
