Your problem is not the reference issue.  D has a limit on how big
static arrays can be in a function.  You can make them bigger by 
declaring them
globally, but I think even that has a limit.  Try this:

import std.stdio;

enum A = 65536;
enum B = 32;

alias MyType = int[A][B];

void foo(ref MyType arr)
{
     writeln(arr[3][3]);
}

MyType arr;
void main()
{
     writeln("arr[3][3] = ", arr[3][3]);
     foo(arr);
}
