That is precisel where I disagree.
The current representation forces uses of integer as index.
And I'm back to my question: when you index the vtable with value 2,
what is the meaning of value 2? You have not answer that question so far;
except saying you are opposed to any change.

Why does that cost more than what you have proposed so far?

I was looking more for feedback than convincing you -- I don't think I
can convince you of anything.
