Use SCM_VECTOR_REF, SCM_VECTOR_SET and SCM_VECTOR_LENGTH instead.
** scm_vector_elements / scm_vector_writable_elements take a single argument that must be a vector.
** The vector argument to scm_vector_elements / scm_vector_writable_elements must be a true vector. Handle/inc arguments have been removed.
Use scm_array_get_handle and scm_array_handle_elements / scm_array_handle_writable_elements on general arrays.
Use scm_c_vector_length to get the length of a vector.
