An aggregate type

struct A {
    int x;
    int y;
    int z;
};

Initialize type with designated initializers

1	`A a{.x = 1, .y = 4, .z = 2};`

List initialization

1	`A c{1, 2, 3};`

Nested type

struct B {
    int x;
    A y;
    int z;
};

Nested initialization

1	`B d{.x = 1, .y = {2, 6, 5}, .z = 3};`
