To be more precise, a dynamic array in D is essentially

struct Array(T)
{
    size_t length;
    T* ptr;
}

So, the length is stored directly in the struct, and the data is referenced
via the pointer stored in the struct. As such, we often refer to a D dynamic
array as a pseudo-reference type. Either way, while the way it's put
together has some very useful properties (like making it so that multiple
dynamic arrays can be slices of the same data), there's no question that it
can be confusing at first. And of course, that extends to strings, since D
strings are dynamic arrays.
