Objects are kind of overkill when you just need a modifyable array. And
copying an array when you just need to add one value to a K-size array
is still not a good idea for many apps. O(n) vs O(n^2) still matters.
One should definitely be careful not to overuse refs, but there are
still valid cases for using them.
