--- Comment #1 from Jacob Carlborg <doob at me.com> ---
Update the D code for the latest compiler:

extern (C) int printf(in char*, ...);

struct Bar
{
    int a, b, c, d, e;
}

extern (Objective-C)
extern class Foo
{
    static Foo alloc() @selector("alloc");
    Foo init() @selector("init");
    Bar getValue() @selector("getValue");
}

void main()
{
    auto f = Foo.alloc.init;
    auto b = f.getValue;
    printf("%d\n", b.a);
}
