Excuse me if I miss something obvious, but:

{
auto copy = arr; //arr's (and copy's) reference counts
are both 2
arr = RCArray!int([]); // There is another owner, so arr

That's a problem, thanks very much for pointing it out. -- Andrei
Again, I think this is an issue with the expectation of RCArray. You
cannot *save* a ref to an array element, only a ref to the array itself,
because you lose control over the reference count.
I don't think arr[0] should correctly bind to foo's second argument.
