But why i´m overwriting the struct if its the first time i´m
putting it there? (like on the array).
There's a difference between initialization and assignment.
```
// Given this structure
struct MyStruct { int x; }
// Both of these lines are initializstion
auto mystruct1 = MyStruct(10);
MyStruct mystruct2;
assert(mystruct1.x == 10);
assert(mystruct2.x == 0);
// And both of these are assignments.
mystruct2 = MyStruct(11);
mystruct1 = mystruct2;
assert(mystruct2.x == 11);
assert(mystruct1.x == 11);
```
If x were immutable, both initializations would succeed, but both
assignments would fail.
