Nope. Arrays do, as they are simply C arrays (T*) with a length
attached, and some fancy goings-on behind the scenes.

Basically, in C, the equivalent would be

typedef struct array {
     int* ptr;
     int length;
};

If I wanted something other than an array, such a structure
makes little sense. Especially seeing as most anything other
than a dynamic array could be stack-allocated, and we don't
want any pointers to stack stuff to escape for long.
