What destructuring binds? I didn't hear about that before.

```C++
#include <iostream>

struct Point {
    int x, y;
};

Point add_points(const Point& a, const Point& b)
{
    return { a.x + b.x, a.y + b.y };
}

int main()
{
    const auto [x, y] = add_points({ 1, 10 }, { -60, 40 });
    std::cout << "x is: " << x << '\n';
    std::cout << "y is: " << y << '\n';
}
```

It seems complex, I didn't get it yet, I wished I didn't ask about it :)

It's really trivial.
`auto [x, y] = getpoint();` is equivalent to
```C++
auto _p = getpoint();
auto x = _p.x /* first element of the struct */;
auto y = _p.y /* second element of the struct */;`
```
Also works with arrays.
```C++
int[] arr = { 10, 12, 14 };
const auto [x, y, z] = arr;
/* x=10 y=12 z=14 */
```
A lot of programming languages have this.
