I guess I see what is going on. Since Array is a struct, a
local copy is made and that never ends up updating the

How can I use it then like an object so this is not a problem?
returning by ref may do what you want:
@property std.container.Array!int arr() { return _arr; }
->
@property ref std.container.Array!int arr() { return _arr; }
As dicebot says, however, the issue is a bit more subtle.
An `Array` is actually little more than a pointer to a payload.
Passing by value is "almost" free, and updating a copy *should*
update the original...
...that is, if it wasn't for the "Gotcha" that the `Array` needs
to be initialized first.
But overall, by ref should be just fine.
