Re: use of vtbl

It is quite possible that such a thing might have been considered but
rejected, as knowledge about the underlying binary structure is
sometimes needed, for example in distributed programming (or rather,
how to translate via a common binary common model). The current C++
standard does not include anything about the underlying binary
implementation expect, C style, some limits (including the size of the
bytes).


But the distributed programming support part is now a task for the
next C++ revision. So it may happen that such questions about the
underlying binary model moves up on the agenda.


As for the vtbl, the C++ standard does not mention it, and thus one is
free to choose another implementation.
