If you need to do these things manually, then what's the point in using
vala? It's the job of compilers.
People who like to do the job of compilers manually should use GObject/C
instead.
Manually filling a virtual function table and calculate offset of
pointers are really of fun. lol

I've read how GObject define virtual methods, in the XClass struct, and
I'm afraid defining new virtual method can break ABI. Am I right?
Before:
struct _XClass
{
GObjectClass parent_class;
/* stuff */
void (*do_action) (X *self, /* parameters */);
};
After:
struct _XClass
{
GObjectClass parent
