Is it possible to support structual bind like [a, b, ...] = x;

[quanzhou]

auto [a, b, ...] = x;
auto [a, ..., b] = y;
auto [...,a, b] = z;

helps to get the last member variable of the right side type.

I do not understand what it means. Can you describe a problem
and then write short example program that solves the problem
using that feature?
