If you test every time you add one element, that's still O(n) tests
where n is the size of the array, the only benefit is that it is not
checked for each calls to a function. But now we are talking about
attaching non-trivial types to variables, and non-trivial checks in a
lot of places (think references etc..), let's not go there...
