No, r is a pointer, not a reference. D does not have reference
variables.
But now the semantics of using the array completely change and
errors abound!

Arrays are (ptr,length) pairs. r is a copy of them:
#! /usr/bin/env rdmd
import std.stdio;
struct X { int[] a; }
void main() {
struct Y { double q; }
struct X { Y[] a; }
X x;
auto r = x.a;
r is not a reference?!?!
When updating x.a, r is not updated ;/ [I'm not sure if it just
creates a slice or what]
