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.
Really, I'm not sure I'm understanding this syntax `auto [x, y]
= getpoint();`, if you have the name of term of it in D or an
explaining link.
D does not have it. You have already been told that when they
have been mentioned.
If you want more information about it in C++, you could read
https://en.cppreference.com/w/cpp/language/structured_binding or,
for javascript,
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment.
That was just meant to be a simple example to show what jfondren
meant with "destructing bindings".
