write-sequence sequence stream &key start end ⇒ sequence
| sequence | a sequence. |
| stream | an output stream. |
| start, end | bounding index designators of
sequence. The defaults for start and end are 0 and nil, respectively.

write-sequence writes the elements of the subsequence of sequence bounded by start and end to stream.

Modifies stream.
Should be prepared to signal an error of type type-error if sequence is not a proper sequence. Should signal an error of type type-error if start is not a non-negative integer. Should signal an error of type type-error if end is not a non-negative integer or nil.
Might signal an error of type type-error if an element of the bounded sequence is not a member of the stream element type of the stream.
write-sequence is identical in effect to iterating over the indicated subsequence and writing one element at a time to stream, but may be more efficient than the equivalent loop. An efficient implementation is more likely to exist for the case where the sequence is a vector with the same element type as the stream.
