> Return destructively modified SEQUENCE or a freshly allocated
> sequence of the same class as SEQUENCE of length LENGTH. Elements
> of the returned sequence are initialized to INITIAL-ELEMENT, if

> to the elements of SEQUENCE if neither is supplied. Signals a
> PROTOCOL-UNIMPLEMENTED error if the sequence protocol is not
> implemented for the class of SEQUENCE.
