But there is (or shouldn't be) anything special about a one-dimensional
array (presuming you intend to allow arrays with more dimensions). And the
"abstraction" you talk about is selecting a bunch of barely related elements
from a multi-dimensional array.

Exactly. If you don't know how large something will grow to, it's better to
allocate it in pieces than to copy it each time it grows.
