until now: it maps JSON dictionaries to alists (instead of hash tables),

adjusting all the existing code to this new mapping.

lists.
(module-&gt;dist-name): Use 'json-fetch' instead of 'json-fetch-alist'.

instead of 'json-fetch-alist'.
(lts-package-version): Use 'vector-&gt;list'.

(alist-&gt;package): Pass 'vector-&gt;list' on the inputs fields, and default
to the empty vector.
* guix/scripts/import/json.scm (guix-import-json): Remove call to
'hash-table-&gt;alist'.
* guix/swh.scm (define-json-reader): Expect pair? or null? instead of
hash-table?.
[extract-field]: Use 'assoc-ref' instead of 'hash-ref'.
(json-&gt;branches): Use 'map' instead of 'hash-map-&gt;list'.
(json-&gt;checksums): Likewise.
(json-&gt;directory-entries, origin-visits): Call 'vector-&gt;list' on the
result of 'json-&gt;scm'.
* tests/import-utils.scm ("alist-&gt;package with dependencies"): New test.

* gnu/installer.scm (installer-program)[installer-builder]: Likewise.
* gnu/installer/locale.scm (iso639-&gt;iso639-languages): Use 'assoc-ref'
instead of 'hash-ref', and pass vectors through 'vector-&gt;list'.
(iso3166-&gt;iso3166-territories): Likewise.
