It's exactly the same.
Lisp-programmer explains the usefulness of fill-pointers as
follows:
"Fill pointer "cuts" the tail of the vector.
In D: .length "cuts" the tail of the vector.
For example, vector elements 100, but if you set the fill
pointer equal to 3, the length of the array (returned by
length) will be equal to 3. The remaining elements are not
visible.

.capacity tells you "real" size of the buffer while .length is
like that fill pointer.
