In C, you only have to specify the top level type:

struct Foo {
     int x;
};

struct Bar
{
     struct Foo f[2];
};

int main()
{
     struct Bar b;
     b = (struct Bar){{{1}, {2}}};
     // or just
     b = (struct Bar){{1, 2}};
     return 0;
}

In D, you would have to:

b = Bar([Foo(1), Foo(2)]);
