Ok, it's like I though final class and struct are equivalent
when calling a method (except the pointer deference, but it's

I don't think there is a real performance problem for us, it's
more about to learn how to have a clean design.
They are equivalent when calling directly through class instance.
When called though interface pointer, final class still results
in vtable dispatch (because type system can't know stored class
is final)
But if you need to inherit from existing interface it is best
thing you have anyway.
