The benefit of having the field specifiers of make-rtd, rtd-constructor,
rtd-field-names, and rtd-all-field-names be lists is: lists fit with all
the sequence-related things, both in standard Scheme and in others'
libraries, which use lists and not vectors.  E.g., memq for looking for
a field name, filter, append, reverse, etc.

Unless there's a compelling reason to use vectors, why not use Scheme's
natural sequence type: the list?
