I don't see how you could argue that they don't have
multi-dimensional arrays.
I'd guess he's contrasting with the semantics offered by
array-oriented languages. For example, can you determine the
rank of those arrays programmatically in constant time? Does the
type system understand the shape, and can it be reshaped
trivially? Does an operator or function expecting rank n
automatically lift to higher ranks? That sort of stuff.
Maybe D does something I haven't learned about (yet) in that
area, but I know C and C++ do not (hence the heap corruption I've
been hunting all week).
