Regarding your immediate need for a growable vector type, Guile implements VLists <https://www.gnu.org/software/guile/manual/html_node/VLists.html>, which can take the place of standard lists, but also offer constant- time index referencing like vectors. VLists are functional data structures and are thus immutable, but this is natural for idiomatic Scheme code.
