I came up with the following. It seems idiomatic to me, but there might be
something smarter:

struct pippo {
   ushort a;
   ushort b;
   ubyte[170] c;
   uint d;
}

void do_something(void[] foo) {
	pippo* p = cast(pippo*)foo.ptr;
	assert (p.d == 2);
}

void main() {
	pippo p;
	p.d = 2;
	do_something((&p)[0..pippo.sizeof]);
}
