This was not primarly a discussion about the advantages of each
programming language but about native arrays which are part of both
languages. It is also highly relevant to this study group
which approach C++ takes here. If C++ decides to treat
these as a legacy concept only it will be difficult to
maintain compatibility in this area.

I would also like such a feature and it seems simple and
unproblematic.

I agree, we should think about deprecating these.
