+It is an error if any element of @var{vector} is not a character.

+The @code{vector->string} procedure returns a newly allocated string
+of the objects contained in the elements of @var{vector} between
+@var{start} and @var{end}.  The @code{string->vector} procedure
+returns a newly created vector initialized to the elements of the

+In both procedures, order is preserved.
