What's the right syntax? This prints three times 28:


struct Foo1 {
    align(1):
        ushort a,b,c,d,e;
        uint f, g, h;
        ushort i, j;
}
pragma(msg, Foo1.sizeof);

struct Foo2 {
    align(1) {
        ushort a,b,c,d,e;
        uint f, g, h;
        ushort i, j;
    }
}
pragma(msg, Foo2.sizeof);

struct Foo3 {
    align(1) ushort a,b,c,d,e;
    align(1) uint f, g, h;
    align(1) ushort i, j;
}
pragma(msg, Foo3.sizeof);

void main() {}



While this prints 26:

align(1) struct Foo4 {
    align(1):
        ushort a,b,c,d,e;
        uint f, g, h;
        ushort i, j;
}
pragma(msg, Foo4.sizeof);
void main() {}
