This code doesn't work:
-------------------------------------
import std.typecons, std.stdio;

struct A {
    void foo(ref ubyte[] a) { a = [1]; }
}
struct B {
    A a;
    mixin Proxy!a;
}
void main() {
    B b;
    ubyte[] a;
    b.foo(a);
    assert(a.length == 1);
}
-------------------------------------
