If I read this closely, I think you're suggesting that 'self' should be
passed as first argument automatically if 'self' is used in a :vtable sub.
However, I would say that in many cases this would not be needed (or
'wrong'); you wouldn't be able to do normal sub calls, without passing
'self'. Maybe some kind of pseudo syntax ('super' comes to mind, but that
implies an inheritance relationship), if you want to call the sub that
you're overriding.

Maybe I'm completely misunderstanding this, in which case you can safely
ignore this :-)
