Yes, but this is C++ not C,=C2=A0 and we are trying to mak= e C++ more modern not stick with the past, right?

And index notion looks anything but elegant solutio= n. That is my opinion of course.

=C2=A0
You =C2=A0might not find it elegant, but it is a feature that has bee= n present in C for some time (to initialize objects) so there is prior art.= It is also tested and the shortcomings are known --at least for initializa= tion, which is not really the same as defaulting arguments to functions or = constructors.
