struct Foo
{
    static assert(Foo.sizeof == 4);  // ok
    pragma(msg, Foo.sizeof);  // Error: struct test.Foo no size yet for forward
reference

    int x;
}

void main() { }

I'm not sure if it's genuinely a bug, IOW maybe the pragma is evaluated before
the compiler does a pass to see which fields the struct is holding?
