Listen to Mike. This is not specific to D and they are only
arrays in name.
I want to provide other examples because I think I come across
this with other words in English. Where one thing uses the name
of another, but there really isn't enough similarities that it
would make sense to refer to them in the same bucket.
In your case though it is similar to square vs rectangle. If you
are trying to understand some properties about squares, you could
talk about having a rectangle, but it is more helpful to be
specific. Consider asking how to find the area of a rectangle,
you'll get the answer "length * height" while asking to finding
the area of a square you might get "length^2"
